SA5232D/01,118

Instrumentation, Op Amps, Buffer Amps Overview

The SA5232D/01,118 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 is typically 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 swings within 50 mV of both rails across the entire power supply range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix '118' against official manufacturer documentation to confirm tape and reel packaging specifications. Confirm that the SA5232D variant meets the required -40 °C to +85 °C operating temperature range for your design. Ensure compatibility with SOIC-8 surface mount assembly processes. Cross-reference the datasheet revision date to validate electrical characteristics against current production standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits requiring rail-to-rail performance under low voltage conditions. The dual configuration allows for cost-effective implementation of differential stages or dual-channel signal processing. Consider the 2.5 MHz bandwidth and 0.8 V/μs slew rate for moderate-speed signal applications. Evaluate thermal dissipation requirements based on the SOIC-8 package thermal resistance if operating near maximum ratings.

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 SA5232 designation specifically denotes the industrial temperature grade (-40 °C to +85 °C) housed in an 8-pin plastic small outline package. It serves as a low-voltage alternative to traditional bipolar op-amps, offering improved efficiency and signal swing capabilities for modern portable and automotive electronic designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The NE5232D is a functionally similar device within the same family but is rated for commercial temperature range (0 °C to +70 °C). Verify that the lower temperature limit of the NE5232D does not compromise system reliability in environments below 0 °C. Pinout compatibility remains identical between these variants.
