LM10CH

Overview

The LM10CH is a monolithic integrated circuit combining a precision operational amplifier and a bandgap voltage reference. It features a single op-amp channel with a gain-bandwidth product of 90 kHz and a slew rate of 0.2 V/µs. The input offset voltage is specified at 2 mV, with an input bias current of 20 nA. It operates on supply voltages ranging from 1.1 V to 40 V, drawing an operating supply current of 270 µA. The device provides a common-mode rejection ratio between 90 dB and 102 dB and delivers up to 20 mA output current per channel.

Feature Summary

• Integrates a precision operational amplifier with a stable bandgap voltage reference on a single die
• Supports low-voltage operation starting from 1.1 V supply rails
• Provides high common-mode rejection ratio for signal integrity
• Delivers sufficient drive capability with 20 mA output current

Applications

• Low-voltage sensor signal conditioning circuits
• Battery-powered instrumentation systems
• Precision data acquisition front-ends
• Voltage reference buffering applications

Procurement Notes

Verify the specific suffix 'CH' against the manufacturer's official datasheet to confirm package type and temperature range specifications. Ensure compatibility with the required SOIC-14 footprint and surface-mount assembly processes. Cross-reference electrical parameters such as input offset voltage and supply current limits with the latest Texas Instruments documentation to guarantee design compliance.

Selection Notes

Select this component when a combined op-amp and voltage reference solution is required in a compact form factor. It is suitable for designs needing low quiescent current and wide supply voltage flexibility. Consider the 90 kHz bandwidth and 0.2 V/µs slew rate for moderate-speed applications. Verify that the SOIC-14 package meets the thermal and spatial constraints of the target PCB layout.

Part Context

This part belongs to the LM10 family of mixed-signal analog devices manufactured by Texas Instruments. It is designed to replace discrete solutions requiring separate amplifiers and references. The device integrates industry-standard precision amplifier characteristics with a reliable internal reference, simplifying circuit design for portable and industrial electronics.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the LM10 series. Verify if other manufacturers offer equivalent dual-function parts with matching electrical specifications and package dimensions.
