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.
