LM101AJ

Overview

The LM101AJ is a single-channel operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 1 MHz and a slew rate of 500 mV/us. The input offset voltage is specified at 2 mV, with an input bias current of 75 nA. It operates on a supply voltage range from 10 V to 44 V. The device draws an operating supply current of 1.8 mA per channel and provides an output current capability of 25 mA. Common-mode rejection ratio is 96 dB, and input voltage noise density is 15 nV/sqrt Hz. It is housed in a TO-99-8 through-hole package.

Feature Summary

• Single-channel operational amplifier architecture
• Through-hole mounting via TO-99-8 package
• High common-mode rejection ratio performance

Applications

• General-purpose analog signal processing circuits
• Voltage amplification stages requiring high CMRR
• Precision instrumentation front-ends

Procurement Notes

Verify the specific suffix 'AJ' against the manufacturer's current datasheet to confirm exact electrical tolerances and temperature ranges. Ensure the TO-99-8 metal can package is compatible with the target PCB or chassis layout. Confirm RoHS compliance status if required by the end-use application regulations. Cross-reference the ordering part number with official Texas Instruments documentation to avoid substitution errors.

Selection Notes

Select this component when a single op-amp with moderate bandwidth and low noise is required. The TO-99-8 package necessitates through-hole assembly methods. Consider the 10 V to 44 V supply range constraints during power budgeting. Evaluate the 25 mA output current limit against load requirements. Compare input bias current specifications against other precision amplifiers if leakage currents are critical to the circuit design.

Part Context

The LM101 series represents a classic operational amplifier family known for internal frequency compensation and high gain. The LM101AJ variant specifically denotes a military or high-reliability grade version within the Texas Instruments portfolio. It shares functional similarities with earlier industry-standard op-amps but offers distinct electrical characteristics such as lower input bias current compared to basic counterparts.
