ADS1282IPWR from Texas Instruments is a Integrated Circuit Ultra-high-resolution 4-kSPS 2-channel delta-sigma ADC with PGA for seismic and energy exploration - Precision ADCs. The ADS1282 is an extremely high-performance, single-chip analog-to-digital converter (ADC) with an integrated, low-noise programmable gain amplifier (PGA) and two-channel input multiplexer (mux). The ADS1282 is suitable for the demanding needs of energy exploration and seismic monitoring environments. The converter uses a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator that provides outstanding noise and linearity performance. The modulator is used either in conjunction with the on-chip digital filter, or can be bypassed for use with post processing filters. The flexible input MUX provides an additional external input for measurement, as well as internal self-test connections. The PGA features outstanding low noise (5 nV/√ Hz) and high input impedance, allowing easy interfacing to geophones and hydrophones over a wide range of gains. The digital filter provides selectable data rates from 250 to 4000 samples per second (SPS). The high-pass filter (HPF) features an adjustable corner frequency. On-chip gain and offset scaling registers support system calibration. The synchronization input (SYNC) can be used to synchronize the conversions of multiple ADS1282s. The SYNC input also accepts a clock input for continuous alignment of conversions from an external source. Together, the amplifier, modulator, and filter dissipate 25 mW. The ADS1282 is available in a compact TSSOP-28 package and is fully specified from -40°C to +85°C, with a maximum operating range to +125°C.

ADS1287DIRHBR from Texas Instruments is a Low-power 1-kSPS 2-ch (simultaneous) delta-sigma ADC with PGA for seismic and energy exploration - Precision ADCs. The ADS1287D device is a dual, simultaneous-sampling, analog-to-digital converter (ADC), with an integrated programmable gain amplifier (PGA) and finite-impulse-response (FIR) digital filter. The ADC is suitable for the demanding needs of low-power, seismic data acquisition. The ADC features a programmable-gain, high-impedance amplifier suitable for direct connection of geophone and hydrophone sensors to the ADC over a wide range of input signals (±2.5 V to ±0.156 V). Dual 100-nA current sources are integrated into the ADC inputs for field testing of sensors. The ADC incorporates a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator. The modulator digital output is filtered and decimated by the internal FIR digital filter to yield the ADC conversion result. The FIR digital filter provides data rates up to 1000 samples per second (SPS). The high-pass filter (HPF) removes DC and low-frequency components from the conversion result. On-chip gain and offset scaling registers support system calibration. Total device power consumption is 4.4 mW. The ADC is packaged in a compact 5-mm × 5-mm VQFN package and is fully specified over the -40°C to +85°C temperature range.

DAC904E from Texas Instruments is a Integrated Circuit 14-Bit 165-MSPS Digital-to-Analog Converter (DAC) - High-speed DACs (>10 MSPS). The DAC904 is a high-speed, Digital-to-Analog Converter (DAC) offering a 14-bit resolution option within the family of high-performance converters. Featuring pin compatibility among family members, the DAC908, DAC900, and DAC902 provide a component selection option to an 8-, 10-, and 12-bit resolution, respectively. All models within this family of DACs support update rates in excess of 165MSPS with excellent dynamic performance, and are especially suited to fulfill the demands of a variety of applications. The advanced segmentation architecture of the DAC904 is optimized to provide a high Spurious-Free Dynamic Range (SFDR) for single-tone, as well as for multi-tone signals- essential when used for the transmit signal path of communication systems. The DAC904 has a high impedance (200k) current output with a nominal range of 20mA and an output compliance of up to 1.25V. The differential outputs allow for both a differential or single-ended analog signal interface. The close matching of the current outputs ensures superior dynamic performance in the differential configuration, which can be implemented with a transformer. Utilizing a small geometry CMOS process, the monolithic DAC904 can be operated on a wide, single-supply range of +2.7V to +5.5V. Its low power consumption allows for use in portable and battery-operated systems. Further optimization can be realized by lowering the output current with the adjustable full-scale option. For noncontinuous operation of the DAC904, a power-down mode results in only 45mW of standby power. The DAC904 comes with an integrated 1.24V bandgap reference and edge-triggered input latches, offering a complete converter solution. Both +3V and +5V CMOS logic families can be interfaced to the DAC904. The reference structure of the DAC904 allows for additional flexibility by utilizing the on-chip reference, or applying an external reference. The full-scale output current can be adjusted over a span of 2-20mA, with one external resistor, while maintaining the specified dynamic performance. The DAC904 is available in SO-28 and TSSOP-28 packages.

ADC12C105CISQ/NOPB from Texas Instruments is a Integrated Circuit 12-Bit, 105-MSPS, 1.0-GHz Input Bandwidth Analog-to-Digital Converter (ADC) - High-speed ADCs (≥10 MSPS). The ADC12C105 is a high-performance CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at rates up to 105 Mega Samples Per Second (MSPS). This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and the external component count, while providing excellent dynamic performance. A unique sample-and-hold stage yields a full-power bandwidth of 1 GHz. The ADC12C105 may be operated from a single +3.0V or +3.3V power supply and consumes low power. A separate +2.5V supply may be used for the digital output interface which allows lower power operation with reduced noise. A power-down feature reduces the power consumption to very low levels while still allowing fast wake-up time to full operation. The differential inputs accept a 2V full scale differential input swing. A stable 1.2V internal voltage reference is provided, or the ADC12C105 can be operated with an external 1.2V reference. Output data format (offset binary versus 2's complement) and duty cycle stabilizer are pin-selectable. The duty cycle stabilizer maintains performance over a wide range of clock duty cycles. The ADC12C105 is available in a 32-lead WQFN package and operates over the industrial temperature range of -40°C to +85°C.
