LM10CN

Overview

The LM10CN is a monolithic integrated circuit combining a precision operational amplifier with a bandgap voltage reference. It features a gain-bandwidth product of 1 MHz and a slew rate of 500 mV/us. The input offset voltage is typically 2 mV, with an input bias current of 75 nA. It operates from a supply voltage range of 10 V to 44 V single supply or ±5 V to ±22 V dual supply. The device draws 1.8 mA operating supply current and provides 25 mA output current per channel. Common mode rejection ratio is 96 dB, and input voltage noise density is 15 nV/√Hz.

Feature Summary

• Integrates a high-gain operational amplifier and a precise voltage reference on a single chip
• Provides rail-to-rail input capability for wide common-mode voltage range
• Features low power consumption suitable for battery-operated applications
• Includes internal frequency compensation for stability

Applications

• Precision instrumentation circuits requiring integrated reference
• Active filter designs utilizing the combined op-amp and reference
• Temperature measurement systems using external sensing elements
• Data acquisition front-ends needing stable voltage references

Procurement Notes

Verify the specific suffix CN indicates the commercial temperature grade variant when sourcing. Confirm package type matches design requirements as variations exist within the LM10 family. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the supplier source aligns with Texas Instruments authorized distribution channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when a compact solution integrating both amplification and reference functions is required. Consider the 1 MHz bandwidth and 500 mV/us slew rate for signal processing speed requirements. Evaluate the 10 V minimum supply voltage constraint against available system power rails. Compare the 2 mV offset voltage specification against application accuracy needs relative to other precision op-amps.
