Description
General part information
ADS125H01 Series
The ADS125H01 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), a clock oscillator, and signal or reference out-of-range monitors.
The integration of a wide input range, ±18-V supply PGA and an ADC into a single package reduces board area up to 50% compared to discrete solutions.
Programmable attenuation and 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. A 1-GΩ minimum input impedance reduces error resulting from sensor loading. Additionally, the low-noise and low-drift performance allow direct connections to strain-gauge bridge and thermocouple sensors that are affected by high common-mode voltage.
