The ADEMO141A/ADEMO141B is a low-drift, low-noise, fully-differential amplifier which can be operated as an analog integrator, for use with a PCB-based di/dt current sensor and analog-to-digital converter (ADC). It has a output common-mode voltage of 1.2V and supply voltage of 3.3V. The analog integrator amplifies signal and cancels the frequency dependance of the current sensor. The ADEMO141A/ADEMO141B has high gain, low noise, and excellent common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) specifications, which makes it ideal for high accuracy energy measurement applications. The ADEMO141A/ ADEMO141B is specified over the extended industrial temperature (−40°C to +125°C), and is available in a 8-lead LFCSP.
