16-channel, 24-bit 1MSPS delta-sigma ADC with integrated channel auto-sequencer and FIFO buffer

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.
