TSM102AIDR

Overview

The TSM102AIDR is a mixed-signal integrated circuit from Texas Instruments featuring a dual operational amplifier, dual comparator, and precision voltage reference. It operates within a supply voltage range of 3 V to 30 V with a total supply current of approximately 200 μA per amplifier. The operational amplifiers provide a gain-bandwidth product of 2.1 MHz and a slew rate of 2 V/μs. The device includes an adjustable voltage reference capable of sourcing up to 100 mA, characterized by low temperature drift.

Feature Summary

• Integrates dual operational amplifiers, dual comparators, and a precision voltage reference into a single package for compact power management designs.
• Operational amplifiers feature rail-to-rail input common-mode voltage ranges that include ground potential.
• Voltage reference provides high sink current capability ranging from 1 mA to 100 mA with adjustable output voltage.
• Low supply current consumption supports battery-powered applications while maintaining medium-speed performance.

Applications

• Switch-Mode Power Supplies
• Battery Chargers
• Window Comparators

Procurement Notes

Verify the specific ordering suffix against the official Texas Instruments Package Option Addendum to confirm the exact package type (SOIC or TSSOP) and reel specifications. Ensure the selected variant matches the required A-grade tolerance if precise reference accuracy is critical for the design. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement.

Selection Notes

Select this component when a combined solution for signal conditioning and voltage monitoring is required in space-constrained environments. The inclusion of both op-amps and comparators reduces bill-of-materials count compared to discrete implementations. Consider the 3 V to 30 V operating range and the specific thermal impedance characteristics of the SOIC-16 package for adequate heat dissipation under load.
