The DDC316 is a 16-bit, 16-channel, current-input analog-to-digital converter (ADC). It combines both current-to-voltage and analog-to-digital (A/D) conversion so that 16 separate low-level current output devices (such as photodiodes) can be directly connected to its inputs and digitized.
For each of the 16 inputs, the DDC316 provides a dual-switched integrator front-end. This configuration allows for continuous current integration: while one integrator is being digitized by the on-chip ADC, the other is integrating the input current. Adjustable integration times range from 10µs to 1ms.
The DDC316 provides a serial interface of the output data, either multiplexed onto a single data output pin or parallel on four output pins. The output mode can be selected based on the available integration time.
The DDC316 uses a +5V analog supply and a +3.3V digital supply. Operating over the temperature range of 0°C to +70°C, the DDC316 is offered in a BGA-64 package.
