TSM103WIDT

Overview

The TSM103WIDT is a monolithic dual operational amplifier IC from STMicroelectronics, housed in an 8-SOIC surface-mount package. It integrates one independent op-amp and a second op-amp with its non-inverting input connected to a fixed 2.5V voltage reference. The device operates within a wide power supply range of 3V to 32V or ±1.5V to ±16V. Key electrical characteristics include a typical output impedance of 0.2Ω, sink current capability from 1mA to 100mA, low input offset voltage of 0.5mV typ., medium bandwidth of 0.9MHz unity gain, and low supply current of 350µA per op-amp at 5V.

Feature Summary

• Integrates a precision 2.5V fixed voltage reference on the non-inverting input of one amplifier channel for simplified circuit design.
• Provides high voltage precision with tolerance options of ±0.4% or ±0.7% for the internal reference output.
• Features large output voltage swing capability ranging from ground up to VCC minus 1.5V.
• Includes 1.5kV electrostatic discharge (ESD) protection on inputs.

Applications

• Power supply management systems
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and temperature grade specifications. Confirm that the 8-SOIC package dimensions align with your PCB footprint requirements. Check for RoHS compliance status as defined in the latest product documentation before finalizing procurement orders.

Selection Notes

Select this component when a built-in voltage reference is required to reduce external component count and board space. It is suitable for designs needing a wide single or dual supply voltage range. Consider the 0.9MHz bandwidth and 350µA quiescent current for applications balancing speed and power consumption.

Part Context

This part belongs to the TSM103 family of special purpose amplifiers designed by STMicroelectronics. It is categorized under linear integrated circuits specifically for power management and signal conditioning tasks. The device leverages monolithic integration to combine standard op-amp functionality with a precise reference source.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify functional equivalence regarding the 2.5V reference accuracy and supply voltage limits before substituting.
