SA5232N/01,112

Instrumentation, Op Amps, Buffer Amps Overview

The SA5232N/01,112 is a matched dual high-performance low-voltage operational amplifier manufactured by NXP USA Inc. It features rail-to-rail input and output operation, with the output swinging to within 50 mV of both supply rails across the entire power supply range. The device typically draws 700 μA per amplifier and delivers 5.5 V peak-to-peak across a 600 Ω load. Key electrical specifications include a unity gain bandwidth of 2.5 MHz, a slew rate of 0.8 V/μs, and an input referred voltage noise of 33 nV/√Hz at 1 kHz. The common-mode input voltage range extends 250 mV beyond both supply rails.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix '01,112' against official NXP documentation to confirm package type and temperature range. Confirm RoHS compliance status as historical data may vary. Ensure the component meets the required operating temperature range of -40 °C to +85 °C for the SA series before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring rail-to-rail performance in single or dual supply configurations between 2 V and 5.5 V. It is suitable for battery-powered applications due to low quiescent current. Consider the 2.5 MHz bandwidth and 33 nV/√Hz noise floor for signal conditioning tasks where precision and speed are balanced.

Instrumentation, Op Amps, Buffer Amps Part Context

The SA5232N belongs to the NE/SA/AU5232 family of matched dual operational amplifiers. The 'SA' designation indicates an extended industrial temperature range of -40 °C to +85 °C, distinguishing it from the commercial NE variant (0 °C to +70 °C) and the automotive AU variant (-40 °C to +125 °C). All variants share identical electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the NE5232N for commercial temperature ranges and the AU5232N for automotive-grade requirements. Verify pin compatibility and thermal derating requirements when transitioning between package types such as DIP-8 and SO-8.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the maximum single supply voltage for the SA5232N?

The absolute maximum single supply voltage rating is 7 V, though recommended operating conditions specify a range of +2 V to +5.5 V.

Does the SA5232N prevent output inversion?

Yes, the device includes built-in output inversion prevention circuitry to maintain correct output polarity during startup or fault conditions.
