OPA4241UA

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4241UA is a quad micro-power operational amplifier from the OPAx241 series, housed in a 14-pin SOIC package. It operates on single supplies from 2.7V to 36V or dual supplies from ±1.35V to ±18V. Key electrical parameters include a maximum input offset voltage of ±400μV (at -40°C to +85°C), a quiescent current of 25μA per amplifier, and a gain-bandwidth product of 35kHz. The device features rail-to-rail output swing within 50mV, high common-mode rejection ratio of 124dB, and open-loop gain of 128dB.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'UA' corresponds to the SOIC-14 package variant when sourcing. Confirm that the component matches the OPAx241 family specifications rather than the OPAx251 series, as performance metrics like offset voltage are optimized for different supply voltages. Ensure the operating environment stays within the specified temperature range of -40°C to +85°C for guaranteed electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside high precision in portable systems. The quad configuration allows multiple channels in a compact surface-mount package. Consider the OPA4251 if operation at higher supply voltages like ±15V is primary, as it offers better offset performance at those levels. Verify capacitive load requirements against stability charts provided in the datasheet.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx241 family, which is specifically laser-trimmed for low offset voltage and drift at a low supply voltage of 5V. It complements the OPAx251 series, which is optimized for ±15V operation. Both families share similar architectural features but differ in initial trimming conditions to suit their respective target supply ranges.
