SA5232D/01,112

Instrumentation, Op Amps, Buffer Amps Overview

The SA5232D/01,112 is a matched dual high-performance low-voltage operational amplifier manufactured by NXP Semiconductors. It operates within a single supply voltage range of +2 V to +5.5 V or a dual supply range of ±1 V to ±2.75 V. The device features a unity gain bandwidth of 2.5 MHz and a slew rate of 0.8 V/μs. Input bias current typically measures 75 nA, with an input offset voltage of 4 mV. Power consumption is approximately 2 mA per amplifier at 5.5 V. The component supports rail-to-rail input and output operation, providing signal swing within 50 mV of both rails. It is housed in an 8-pin Plastic Small Outline (SO) package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm the temperature range and package type. The SA5232D variant indicates an industrial temperature range of -40 °C to +85 °C. Confirm availability status as manufacturing lifecycles may have changed since the original datasheet publication. Ensure compatibility with existing PCB footprints for the SO-8 package before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail performance is required in low voltage environments. It is suitable for designs needing wide common-mode input ranges exceeding standard supply limits. Consider the 2.5 MHz bandwidth and 0.8 V/μs slew rate for moderate speed signal processing tasks. Evaluate thermal dissipation requirements based on the SO-8 package thermal resistance characteristics under maximum load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the NE/SA/AU5232 family of matched dual operational amplifiers originally developed by Philips Semiconductors. The 'SA' designation specifically denotes the industrial temperature grade (-40 °C to +85 °C). The 'D' suffix identifies the 8-pin Plastic Small Outline package. This series was designed to provide high performance in low voltage applications where traditional op-amps fail to utilize the full supply range.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include the NE5232D for commercial temperature range applications and the AU5232D for extended automotive temperature ranges. All variants share identical pinouts and electrical characteristics except for operating temperature limits. Verify that the replacement package matches the SO-8 footprint.
