TSM103WAID

Overview

The TSM103WAID is a monolithic integrated circuit from STMicroelectronics, housed in an 8-SOIC surface-mount package. It integrates one independent operational amplifier and a second op-amp with its non-inverting input connected to a fixed 2.5V voltage reference. Key electrical parameters include a typical input offset voltage of 0.5mV, a unity-gain bandwidth of 0.9MHz, and a supply current of 350µA per op-amp at 5V. The device supports a wide power supply range of 3V to 32V or ±1.5V to ±16V, features 1.5kV ESD protection, and offers a large output voltage swing from 0V to VCC-1.5V.

Feature Summary

• Integrates a dual operational amplifier configuration with a dedicated 2.5V fixed voltage reference channel
• Provides high voltage precision with options for ±0.4% or ±0.7% tolerance on the reference output
• Features low input offset voltage and medium bandwidth suitable for general-purpose signal processing
• Includes robust 1.5kV electrostatic discharge protection for enhanced reliability

Applications

• Power supply management systems
• Data acquisition systems
• Secondary side switch-mode power supply control
• LED driver circuits

Procurement Notes

Verify the specific suffix 'AID' against the manufacturer's official datasheet to confirm pinout compatibility and functional specifications. Ensure the selected component meets the required operating temperature range and voltage precision class (±0.4% or ±0.7%) for the target application. Cross-reference the ordering information with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when space and cost savings are critical due to its monolithic integration of amplifiers and a voltage reference. It is suitable for applications requiring a stable 2.5V reference alongside signal conditioning. Consider the 0.9MHz bandwidth and 350µA supply current when designing for moderate speed and low power consumption requirements within the 3V to 32V supply range.

Part Context

The TSM103W series is designed by STMicroelectronics as a specialized amplifier IC for power management and data acquisition. The TSM103WAID variant specifically denotes the 8-SOIC package version. This family combines standard op-amp functionality with a built-in reference, reducing the component count in designs that require precise voltage monitoring or regulation.

Replacement Considerations

Check for direct substitutes within the TSM103W family, such as TSM103WID, ensuring package and suffix compatibility. Verify if alternative dual op-amps with integrated references meet the 2.5V reference precision and bandwidth requirements.
