Key Features

  • Dual op-amp with integrated voltage reference in a compact SO-8 package
  • 70 dB minimum CMRR with 85 dB typical for strong noise rejection in precision circuits
  • Low 0.2 µA max input bias current enabling accurate high-impedance signal amplification

Applications

The TSM103WIDT is designed for precision analog signal conditioning applications such as battery-powered sensor interfaces and industrial measurement front-ends where low input bias current and stable reference voltage are critical. Its 70 dB minimum CMRR makes it well suited for differential signal amplification in noisy environments. The compact SO-8 footprint suits space-constrained designs in portable instruments and smart meters.

Frequently Asked Questions

What is the input bias current specification of the TSM103WIDT, and why does it matter for high-impedance sensor interfaces?

The TSM103WIDT specifies a maximum input bias current of 0.2 µA at 25°C, with a typical value of 0.15 µA. Such low bias current minimizes voltage error across high-impedance source resistances, making the device suitable for interfacing with resistive sensors above 100 kΩ without introducing significant offset errors.

How does the CMRR performance of the TSM103WIDT benefit industrial differential measurement designs?

With a minimum CMRR of 70 dB and a nominal 85 dB, the TSM103WIDT strongly rejects common-mode noise present on both input lines simultaneously. In 4-20 mA industrial loops or bridge sensor readouts operating at 5 V, this level of rejection ensures that 50 Hz or 60 Hz interference does not corrupt the differential measurement signal.

When is the TSM103WIDT in an SO-8 package a practical choice compared to larger dual op-amp packages?

The SO-8 package occupies roughly 5 mm × 4 mm of board space, which is significantly smaller than DIP-8 alternatives while still providing 8 accessible pins for dual-amplifier and reference connections. This makes TSM103WIDT a practical choice for compact PCB designs where a 16-week factory lead time is acceptable and space below 20 mm² is a hard constraint.
