TSM102AIDG4

Overview

The TSM102AIDG4 is a mixed-signal integrated circuit combining a dual operational amplifier, a dual comparator, and a precision voltage reference. It operates on a single supply voltage ranging from 3 V to 30 V with a total supply current of approximately 200 µA per channel. The device features rail-to-rail input common-mode voltage range including ground, low output saturation voltage, and latch-up immunity. The A-grade version offers a tight voltage reference tolerance of 0.4% at 25°C.

Feature Summary

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and reel specifications. Ensure the selected variant matches the required voltage reference tolerance grade (A-grade or standard) for your application. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement to align with assembly process requirements.

Selection Notes

Select this component when a compact solution integrating analog signal conditioning, threshold detection, and a stable reference voltage is required. The low quiescent current makes it suitable for battery-powered applications. Verify that the 2.1 MHz gain bandwidth product and response times meet the speed requirements of your sensing or control loops.

Part Context

This device belongs to the TSM102 family, which consolidates multiple building blocks typically found in power management circuits. By integrating these functions, it reduces component count and board space compared to discrete implementations. The family supports various packages including SOIC and TSSOP to accommodate different layout constraints.
