Frequently Asked Questions
What CMRR specification does the TSC101AILT provide and how does it reduce errors in low-side current sensing?
The TSC101AILT achieves a typical CMRR of 105 dB and a minimum of 90 dB, meaning common-mode supply voltage variations are attenuated by over 30,000 times before reaching the output. In low-side shunt current sensing with a 50 mΩ resistor, this level of rejection prevents ground bounce of even 1 V from introducing more than a few microvolts of measurement error at the amplifier output.
How does the 2.3 mV maximum offset voltage of the TSC101AILT affect accuracy when measuring small shunt voltages?
With a 2.3 mV maximum input offset voltage, the TSC101AILT introduces at most 2.3 mV of systematic error at the differential input. For a 10 mΩ shunt sensing 1 A (10 mV signal), this offset represents a 23% worst-case error, so designers targeting sub-5% accuracy should use a larger shunt of at least 50 mΩ or apply offset trimming to stay within budget.
For a compact motor driver PCB, how much board space does the TSC101AILT SOT-23 package require compared to larger current-sense amplifier packages?
The TSC101AILT occupies a 5-pin SOT-23 footprint of approximately 2.9 mm × 1.6 mm, which is roughly 4 times smaller than an SO-8 package footprint of about 5 mm × 6 mm. This area saving is significant in motor driver PCBs where current-sense circuits compete for space with gate drivers, bypass capacitors, and thermal relief pads around power FETs.
