TSM103ID

Overview

The TSM103ID is a monolithic dual operational amplifier integrated circuit manufactured by STMicroelectronics. It integrates one independent op-amp and a second op-amp with its non-inverting input connected to an internal 2.5V fixed voltage reference. The device features a wide power supply range of 3V to 32V or ±1.5V to ±16V, low input offset voltage (typical 0.5mV), and medium bandwidth (unity gain 0.9MHz). It offers low supply current (350µA/op at VCC=5V) and large output voltage swing from 0V to (VCC - 1.5V).

Feature Summary

• Integrates a precision 2.5V fixed voltage reference within the dual op-amp structure.
• Provides space and cost savings through combined signal processing and reference generation.
• Features wide power supply compatibility for diverse system architectures.

Applications

• Power supply management systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'ID' against official STMicroelectronics documentation to confirm package type and temperature grade. Ensure the selected variant matches the required operating conditions and pinout configuration for the target application design.

Selection Notes

Select this component when a compact solution combining amplification and a stable voltage reference is required. Consider the 0.9MHz bandwidth and 350µA current consumption for applications balancing performance with power efficiency in single or dual supply environments.

Part Context

The TSM103 series belongs to STMicroelectronics' portfolio of specialized operational amplifiers designed for integrated functions. This family targets applications requiring reduced board space and simplified bill of materials by consolidating multiple analog functions into a single monolithic IC.

Replacement Considerations

Consult official STMicroelectronics substitution guides for verified alternatives. Generic dual op-amps lack the integrated 2.5V reference and require external components to replicate functionality.
