OPA2192IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2192IDR is a dual-channel precision operational amplifier from Texas Instruments, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 4.5 V to 36 V and supports junction temperatures from -40°C to 125°C. Key electrical specifications include a maximum input offset voltage of 5 µV, an input bias current of 5 pA, and a quiescent current of 1 mA per two channels. The device features a gain-bandwidth product of 10 MHz, a slew rate of 20 V/µs, and can deliver an output current of 65 mA per channel with rail-to-rail output capability.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required operating temperature range and pinout configuration for your PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits requiring high precision at elevated voltages up to 36 V. The dual-channel architecture reduces board space compared to single-channel alternatives. Consider the 10 MHz bandwidth and 20 V/µs slew rate for applications demanding moderate speed alongside low noise and high linearity. Verify that the 8-SOIC package dimensions fit the available footprint constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPAx192 series, which includes single-channel (OPA192) and quad-channel (OPA4192) variants sharing identical electrical characteristics. The 'I' designation indicates industrial temperature range performance, while 'D' specifies the SOIC package. The 'R' suffix denotes reel packaging. These devices are engineered for general-purpose precision applications requiring high voltage tolerance and low power consumption.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include OPA192IDR for single-channel needs and OPA4192IDR for quad-channel requirements. Other compatible options may include OPA2197IDR if rail-to-rail input is strictly required with similar precision metrics.
