TSM102IDR

Overview

The TSM102IDR is a dual operational amplifier, dual comparator, and voltage reference integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 30 V and functions across an ambient temperature range of -40 °C to +85 °C. The device features a gain-bandwidth product of 2.1 MHz and a slew rate of 2 V/µs. Input offset voltage is specified at 4.5 mV with a bias current of 100 nA. Common-mode rejection ratio ranges from 70 dB to 90 dB. The package type is SOIC-16.

Feature Summary

• Combines dual operational amplifiers, dual comparators, and a precision voltage reference in a single package for power management applications.
• Operational amplifiers feature rail-to-rail input common-mode voltage range including ground.
• Comparators provide low-level output saturation voltage close to the negative supply rail.
• Voltage reference offers adjustable output voltage capability with latch-up immunity.

Applications

• Switch-mode power supplies
• Battery chargers
• Window comparators
• Alarms, detectors, and sensors

Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-16 tape and reel packaging configuration. Confirm that the standard grade tolerance aligns with application requirements, as this variant differs from the A-grade version. Ensure the operating environment remains within the specified -40 °C to +85 °C temperature range during deployment.

Selection Notes

Select this component when a combined solution for signal conditioning and threshold detection is required. The inclusion of a precision voltage reference reduces external component count. Verify that the 2.1 MHz bandwidth meets system speed requirements. Consider the SOIC-16 footprint constraints against available PCB real estate.

Part Context

This part belongs to the TSM102 family, which integrates analog building blocks for power management. The 'I' designation indicates the industrial temperature grade (-40 °C to +85 °C). The 'D' suffix specifies the SOIC package, while 'R' denotes the reel packaging format used for automated assembly processes.
