TITMCS1101A2BQDR
Overview
The TMCS1101A2BQDR is a galvanically isolated Hall effect current sensor designed for high-precision AC or DC current measurement. It features an 80kHz bandwidth and a ratiometric analog output with 100mV/A sensitivity, making it suitable for systems requiring low drift and high linearity over a wide temperature range. The device includes a zero-drift internal reference and is housed in a compact 8-SOIC package for surface-mount applications.
Why Choose This Part
This sensor offers exceptional accuracy with a linearity of +/-0.05% and an integrated zero-drift reference that minimizes temperature-induced measurement errors. Its 80kHz bandwidth and 6.5us response time provide the speed necessary for high-frequency switching applications while maintaining 330 nV/rtHz noise performance. The galvanic isolation simplifies high-side sensing without the need for complex level-shifting circuitry.
Applications
Key Specifications
Getting Started
To evaluate this part, use the TMCS1101EVM evaluation module which provides a test platform for all sensitivity variants. Connect the analog output to a high-impedance ADC input on a microcontroller and ensure the VDD supply is decoupled with a 0.1uF ceramic capacitor placed close to the device pins. The ratiometric output scales with VDD, so use the same voltage reference for your ADC for maximum measurement precision.
