OP113ES

Instrumentation, Op Amps, Buffer Amps Overview

The OP113ES is a single-channel precision operational amplifier from the Analog Devices OPx13 family, housed in an 8-pin SOIC package. It features a gain-bandwidth product of 3.4 MHz and a slew rate of 1.2 V/µs. Key electrical parameters include an input offset voltage of 75 µV, input bias current of 600 nA, and input voltage noise density of 9 nV/√Hz. The device supports dual-supply operation with a maximum voltage of ±18 V (36 V total) and minimum supply voltages of 2 V or 4 V depending on configuration. It offers a common-mode rejection ratio of 116 dB and power supply rejection ratio of 120 dB, operating within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ES' indicates the SOIC-8 surface-mount package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation as distribution listings may vary. Ensure the ordering part number matches the exact pinout and thermal requirements for your PCB layout. Cross-reference with Analog Devices datasheets to validate performance specifications against your application needs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low noise and low drift are critical for applications involving internal digital calibration. The OP113ES provides sufficient bandwidth for general-purpose precision tasks while maintaining stability in single-supply configurations. Consider the 8-pin SOIC footprint for space-constrained designs requiring surface-mount assembly.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP113ES belongs to the OPx13 series of single-supply operational amplifiers manufactured by Analog Devices. This family is engineered to complement processor-based systems by handling analog imperfections like temperature drift and noise that software calibration cannot address. The ES suffix specifically denotes the plastic small-outline integrated circuit (SOIC) package version.
