These devices are designed for applications like high-precision data acquisition, electric vehicle battery management, motor control, and switch-mode power supplies that demand high-speed and high-resolution analog-to-digital conversion.
The MCP331x1(D)-xx family includes a one megasample-per-second AEC-Q100-qualified 16-bit SAR for industrial applications. The MCP6D11 differential amplifier provides a low-distortion interface.
The MCP331x1(D)-xx family ranges in resolution from 12-, 14-, and 16-bit, with speed options ranging from 500 kilosamples per second to 1 megasample per second.
These devices have a fixed low analog supply voltage (AVDD) of 1.8 volts and 1.6 milliamps typical operation. These devices support a 1.7-to-5.5-volt digital I/O interface voltage (DVIO) range to eliminate the need for using external voltage level shifters. The MCP331x1(D)-xx high-temperature family contains single-ended and differential input voltage measurement options.
Microchip's MCP6D11 differential amplifier is designed to address the challenge of interfacing a small analog signal to a high-speed, high-resolution A/D converter without introducing additional noise and distortion by providing a low-distortion and high-accuracy interface to drive the A/D converter.
The MCP331x1D-XX Evaluation Kit is available to demonstrate the performance of the MCP331x1D-XX SAR A/D converter family devices. The evaluation kit includes MCP331x1D evaluation board; PIC32MZ EF MCU curiosity board for data collection; and SAR A/D converter utility PC graphical user interface (GUI).
