201-000795

201-000795 from Texas Instruments is a Integrated Circuit 32 Channel Current-Input 20-bit ADC - Computer tomography (CT) AFEs. The DDC232 is a 20-bit, 32-channel, current-input analog-to-digital (A/D) converter. It combines both current-to-voltage and A/D conversion so that 32 separate low-level current output devices, such as photodiodes, can be directly connected to its inputs and digitized. For each of the 32 inputs, the DDC232 provides a dual-switched integrator front-end. This configuration allows for continuous current integration: while one integrator is being digitized by the onboard A/D converter, the other is integrating the input current. Adjustable integration times range from 166µs to 1s, allowing currents from fAs to µAs to be continuously measured with outstanding precision. The DDC232 has a serial interface designed for daisy-chaining in multi-device systems. Simply connect the output of one device to the input of the next to create the chain. Common clocking feeds all the devices in the chain so that the digital overhead in a multi-DDC232 system is minimal. The DDC232 uses a +5V analog supply and a +2.7V to +3.6V digital supply. Operating over the temperature range of 0°C to +70°C, the DDC232 BGA-64 package is offered in two versions: the DDC232C for low-power applications, and the DDC232CK when higher speeds are required.
