Description

General part information

ADS125H02 Series

The ADS125H02 is a ±20-V input, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC). The ADC features a low-noise programmable gain amplifier (PGA), an internal reference, clock oscillator, and signal or reference out-of-range monitors.

The integration of a wide input range, ±18-V PGA and an ADC into a single package reduces board area up to 50% compared to discrete solutions.

Programmable gain of 0.125 to 128 (corresponding to an equivalent input range from ±20 V to ±20 mV) eliminates the need for an external attenuator or external gain stages. 1-GΩ minimum input impedance reduces error caused by sensor loading. Additionally, the low noise and low drift performance allow direct connections to bridge, resistance temperature detector (RTD), and thermocouple sensors.
