AD7176-2 Analog-to-Digital Converter

AD7176-2 Analog-to-Digital Converter

Analog Devices' AD7176-2 is a fast settling, highly accurate, high resolution, multiplexed ∑-Δ analog-to-digital converter (ADC) for low bandwidth input signals. Its inputs can be configured as two fully differential or four pseudo differential inputs via the integrated crosspoint multiplexer. An integrated, precision, 2.5 V, low drift (2 ppm/°C), band gap internal reference (with an output reference buffer) adds functionality and reduces the external component count.

The maximum channel scan data rate is 50 kSPS (with a settling time of 20 µs), resulting in fully settled data of 17 noise-free bits. User-selectable output data rates range from 5 SPS to 250 kSPS with resolution increases at lower speeds.

The AD7176-2 offers three key digital filters. The fast settling filter maximizes the channel scan rate. The Sinc3 filter maximizes the resolution for single-channel, low speed applications. For 50 Hz and 60 Hz environments, the AD7176-2 specific filter minimizes the settling times or maximizes the rejection of the line frequency. These enhanced filters enable simultaneous 50 Hz and 60 Hz rejection with a 27 SPS output data rate (with a settling time of 36 ms).
