The ADS125P08 is a multiplexed 8/16-Channel, 24 bit, delta-sigma (ΔΣ), analog-to-digital converter (ADC) with data rates up to 1MSPS and is configurable to accept up to 8 fully differential analog inputs or up to 16 single-ended analog inputs. The device offers an excellent combination of ac performance and dc precision with low power consumption.

The device integrates high-impedance input and reference buffers to reduce signal loading. The ADS125P08 is equipped with a channel auto-sequencer and a FIFO (first-in, first-out) buffer. The power-scalable architecture provides four speed modes to optimize data rate, resolution, and power consumption.

Input and output data and register settings are validated by a cyclic-redundancy check (CRC) feature to enhance operational reliability.

The small 5mm × 5mm VQFN package is designed for limited space applications. The device is fully specified for operation over the –40°C to +125°C temperature range.
