What are the key features of PADS125H02IRHBR?
- 24-bit delta-sigma ADC with 40 kSPS throughput and 0.0012% max linearity error for precision measurement in industrial and instrumentation applications
- ±20 V wide analog input range with integrated PGA enabling direct connection to industrial sensors without external attenuators or level shifters
- Integrated IDACs, GPIOs, and VREF in a compact 32-pin QFN (S-PQCC-N32), reducing external component count and PCB area in precision analog front-end designs
What is PADS125H02IRHBR used for?
PADS125H02IRHBR is designed for precision industrial measurement applications including factory automation sensors, pressure and flow transducers, and 4–20 mA current loop receivers requiring high-resolution digitization. Its ±20 V input range accommodates industrial signal levels directly, while the integrated PGA amplifies low-level bridge sensor outputs prior to the 24-bit ADC for optimal dynamic range. The on-chip IDACs and voltage reference further simplify RTD and bridge excitation circuitry in compact signal conditioning modules.

Frequently Asked Questions
What resolution and sample rate does the PADS125H02IRHBR deliver for precision industrial measurement?
PADS125H02IRHBR achieves 24-bit resolution at up to 40 kSPS across 2 differential input channels, with a maximum linearity error of only 0.0012%. This combination of high resolution and moderate throughput makes it suitable for strain gauge, pressure sensor, and temperature measurement applications requiring sub-ppm noise performance at industrial sampling rates.
How does the ±20 V input range of PADS125H02IRHBR simplify 4–20 mA current loop interface design?
Industrial 4–20 mA transmitters typically produce a 1 V to 5 V signal across a 250 Ω sense resistor or up to ±10 V on bipolar sensor outputs. The PADS125H02IRHBR's ±20 V analog input range accommodates these signals directly without external resistor dividers or op-amp attenuators, reducing component count and eliminating gain error introduced by precision resistor tolerances in traditional front-end circuits.
What role does the integrated PGA play when connecting a Wheatstone bridge sensor to PADS125H02IRHBR?
A 350 Ω Wheatstone bridge excited at 5 V produces a full-scale differential output of only 10 mV to 20 mV. The PADS125H02IRHBR's integrated PGA amplifies this millivolt-level signal to match the ADC's full-scale input range before digitization, boosting effective resolution by several bits and eliminating the need for a separate instrumentation amplifier, which saves $1 to $3 per channel in precision weighing and force measurement designs.
Does PADS125H02IRHBR include an internal voltage reference and how does this reduce BOM cost?
Yes, PADS125H02IRHBR integrates an internal voltage reference (VREF), eliminating the need for a discrete precision reference IC that would typically cost $0.50 to $2.00 per unit. Combined with on-chip IDACs for RTD excitation and GPIOs for multiplexer control, the integrated reference reduces the external component count by 5 or more parts compared to a discrete 24-bit ADC solution in a 2-channel sensor interface design.
