ADS125P08IRHBR

The ADS125P08 is a multiplexed 8/16-channel, 24-bit, Δ-Σ (ΔΣ) ADC with data rates up to 1MSPS, configurable to accept up to 8 fully differential analog inputs or up to 16 single-ended analog inputs. The device offers excellent AC performance, DC accuracy, and low power consumption. It integrates high-impedance input and reference buffers to reduce signal loading. The ADS125P08 features a channel auto-sequencer and a FIFO buffer. The scalable power architecture provides four speed modes to optimize data rate, resolution, and power consumption. Input and output data and register settings are verified through a CRC function to enhance operational reliability. The compact 5mm × 5mm VQFN package is designed for space-constrained applications. The device is rated for an operating temperature range of –40℃ to +125℃.
