OPA827AIDRG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA827AIDRG4 is a single-channel, low-noise, high-precision operational amplifier manufactured by Texas Instruments. It features a JFET input stage with a gain-bandwidth product of 22 MHz and a slew rate of 28 V/us. Key electrical specifications include an input offset voltage of 150 uV, input bias current of 10 pA, and input voltage noise density of 4 nV/sqrt Hz. The device operates on supply voltages ranging from 8 V to 36 V (single) or 4 V to 18 V (dual), consuming 4.8 mA of quiescent current per channel. It provides rail-to-rail output capability and is housed in an SOIC-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number OPA827AIDRG4 against official Texas Instruments documentation to confirm the G4 suffix indicates lead-free/RoHS compliance. Ensure the SOIC-8 package variant matches your PCB footprint requirements. Confirm that the operating temperature range of -40 C to +125 C aligns with your environmental design constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits that demand both low noise and high precision in a single-channel configuration. The JFET input is critical for interfacing with high-impedance sources where bias current errors must be minimized. Consider the 22 MHz bandwidth and 28 V/us slew rate for moderate-speed applications. Verify that the 30 mA output current capability meets the drive requirements of downstream stages without external buffering.
