AMC1204BDWR Description

Short technical summary and product information.

The AMC1204BDWR from Texas Instruments is a 16-bit, isolated delta-sigma modulator designed for precision current-sensing applications. It features a ±250mV input voltage range, optimized for use with shunt resistors. The device operates with a maximum sample rate of 78kSPS and provides a serial interface.

 

Key electrical characteristics include a Signal-to-Noise Ratio (SNR) of 84 dB minimum and a Spurious-Free Dynamic Range (SFDR) of 78 dB. It offers excellent DC precision with an Integral Non-Linearity (INL) of ±8 LSB maximum and a gain error of ±2% maximum. The modulator supports analog and digital voltage supplies of 3.3V and 5V.

 

Designed for robust performance, the AMC1204BDWR has a CMTI of 15 kV/µs and a withstand isolation voltage of 3000 Vrms. It operates across an extended industrial temperature range of -40°C to 125°C. The device is housed in a 16-SOIC package and is suitable for surface mount.

 

This isolated modulator is ideal for applications requiring accurate current measurement in high-voltage or noisy environments, such as motor control, power monitoring, and battery management systems.
