OPA2137E/250

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2137E/250 is a dual-channel J-FET input operational amplifier from the MicroAmplifier series by Texas Instruments. It features a gain-bandwidth product of 1 MHz and a slew rate of 3.5 V/µs. The device operates on supply voltages ranging from 4.5 V to 36 V, with a maximum dual supply of 18 V. Key electrical parameters include an input offset voltage of 1.5 mV, input bias current of 5 pA, and output current per channel of 60 mA. It provides a common-mode rejection ratio of 84 dB and input voltage noise density of 45 nV/sqrt Hz. The component functions within a temperature range of -40°C to 85°C and is housed in an 8-VSSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E' indicates the 8-VSSOP package configuration. Confirm the '/250' designation corresponds to the standard tape-and-reel packaging format. Ensure compatibility with the required operating temperature range of -40°C to 85°C for the intended application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high input impedance and low bias current are required alongside moderate bandwidth. The rail-to-rail performance makes it suitable for single-supply systems where maximizing dynamic range is critical. Compare against the OPA2137UA variant if a SOIC-8 package is preferred instead of the VSSOP form factor.
