The AD7176-2 is a fast settling, highly accurate, high resolution,multiplexed Σ-Δ analog-to-digital converter (ADC) for low bandwidthinput signals. Its inputs can be configured as two fullydifferential or four pseudo differential inputs via the integratedcrosspoint multiplexer. An integrated precision, 2.5 V, low drift(2 ppm/°C), band gap internal reference (with an outputreference buffer) adds functionality and reduces the externalcomponent count.
The maximum channel scan data rate is 50 kSPS/channel(settling time of 20 µs), resulting in fully settled data with17 noise free bits. User-selectable output data rates range from5 SPS to 250 kSPS. The resolution increases at lower speeds.
The AD7176-2 offers three key digital filters. The fast settlingsinc5 + sinc1 filter maximizes the channel scan rate. The sinc3filter maximizes the resolution for single-channel, low speedapplications. For 50 Hz and 60 Hz environments, the AD7176-2specific filter minimizes the settling times or maximizes therejection of the line frequency. These enhanced filters enablesimultaneous 50 Hz and 60 Hz rejection with a 27 SPS outputdata rate (with a settling time of 36 ms).
System offset and gain errors can be corrected on a per channelbasis. This per channel configurability extends to the output datarate used for each channel when using a sinc5 + sinc1 filter. Allswitching of the crosspoint multiplexer is controlled by the ADCand can be configured to automatically control an externalmultiplexer via the GPIO pins.
The specified operating temperature range is −40°C to +105°C.The AD7176-2 is housed in a 24-lead TSSOP package.
