OPA132UAG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA132UAG4 is a single-channel, high-speed FET-input operational amplifier manufactured by Texas Instruments. It features an 8 MHz gain-bandwidth product and a 20 V/us slew rate. The device operates within a supply voltage range of 5 V to 36 V and consumes 4 mA of quiescent current per channel. Key electrical specifications include a maximum input offset voltage of 2 mV, an input bias current of 50 pA, and a common-mode rejection ratio of 100 dB. The input voltage noise density is specified at 8 nV/sqrt Hz. It is housed in an SOIC-8 surface-mount package and supports an operating temperature range from -40 C to +125 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead times. Confirm availability as component lifecycles may change. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Check for moisture sensitivity levels if reflow soldering is planned. Validate that the operating temperature range meets your system's environmental constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance of speed and precision is required for single-channel applications. The FET input provides high impedance and low bias current, making it suitable for high-impedance source interfacing. Compare the 8 MHz bandwidth against higher-speed alternatives if signal integrity at very high frequencies is critical. Consider the rail-to-rail output feature if maximizing signal swing near the supply rails is necessary for your specific circuit topology.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA132 family of general-purpose, high-speed operational amplifiers. It shares architectural similarities with other members like the OPA132U but includes specific manufacturing and compliance suffixes. The family is designed for applications demanding low noise and fast transient response. It serves as a discrete solution for analog signal conditioning tasks where integrated sensor interfaces are not feasible.
