Texas Instruments OPA2172IDRGR

Overview

OPA2172IDRGR from Texas Instruments is a dual precision operational amplifier designed for low-noise signal conditioning, sensor interfaces, industrial measurement, active filtering, and general-purpose precision analog circuits. The device provides low offset voltage, low input bias current, wide supply-voltage operation, rail-to-rail output swing, and stable dual-amplifier integration in a compact VSON package.

As part of the Texas Instruments OPAx172 precision amplifier family, OPA2172IDRGR combines 10MHz gain-bandwidth product, 10V/µs slew rate, low 150µV maximum offset voltage, 5nV/√Hz voltage noise density, high capacitive-load drive capability, and wide 4.5V to 36V single-supply or ±2.25V to ±18V dual-supply operation. For engineers reviewing the OPA2172IDRGR datasheet, OPA2172IDRGR pinout, OPA2172IDRGR application, or OPA2172IDRGR equivalent, this device is widely used in industrial control, data acquisition, sensor signal conditioning, active filters, ADC drivers, audio circuits, and precision analog front-end systems.

Technical Context

In precision analog systems, OPA2172IDRGR operates as a dual low-noise operational amplifier for buffering, gain setting, active filtering, level shifting, sensor conditioning, and ADC input drive. Its 10MHz bandwidth and 10V/µs slew rate support higher-speed signal-chain stages than many lower-power precision op amps, while its low offset voltage and low noise help preserve signal accuracy.

The wide supply-voltage range allows the amplifier to operate from industrial 5V, 12V, 24V, and 36V rails or from split analog supplies up to ±18V. Rail-to-rail output behavior helps maximize signal swing near the supply rails, while the input common-mode range and output-drive capability should still be checked against the required signal amplitude, load impedance, and supply conditions.

OPA2172IDRGR is commonly used in PLC analog input modules, current and voltage sensing circuits, active filters, precision rectifiers, industrial transmitters, data-acquisition front ends, test equipment, and embedded analog signal chains requiring stable dual-channel precision amplification in a small package.

Key Specifications

Pinout & Package

The OPA2172IDRGR pinout follows a compact dual operational amplifier layout in an 8-pin VSON package. The device includes separate inputs and outputs for amplifier A and amplifier B, plus positive and negative supply pins. This package is suitable for dense analog layouts where board area and short signal paths are important.

For PCB implementation, local supply decoupling should be placed close to the supply pins, input traces should be kept short and away from switching nodes, and the exposed thermal pad or package ground strategy should follow the TI layout guidance for the DRG package. Low-leakage board layout, clean grounding, and careful feedback routing are important for maintaining low offset and low-noise performance.

Applications

Equivalent & Alternatives

When evaluating OPA2172IDRGR equivalent devices, engineers should compare amplifier channel count, bandwidth, slew rate, offset voltage, noise density, input bias current, supply-voltage range, output swing, package footprint, temperature range, and stability with capacitive loads.

Compared with OPA2172IDR, OPA2172IDRGR is optimized for compact VSON / DRG package layouts while maintaining the same dual OPA2172 amplifier family behavior. OPA2172IDRGR vs OPA2192IDR selection depends on offset budget, bandwidth target, noise requirement, supply-voltage range, package footprint, power consumption, and sourcing continuity requirements.

Quality

OPA2172IDRGR should be sourced as original Texas Instruments components through traceable and controlled supply channels. Quality verification procedures may include package inspection, top-mark validation, solderability testing, input offset verification, bias-current testing, output swing review, gain-bandwidth confirmation, noise-performance review, and incoming inspection according to precision analog production requirements.

Because the device is used in precision analog signal chains, reliability depends on clean PCB layout, local supply bypassing, stable feedback networks, low-noise grounding, thermal symmetry, input-protection strategy, and separation from switching regulators or high-current traces. Traceable sourcing supports manufacturing quality and reduces counterfeit supply-chain risk for industrial and measurement-system production programs.
