MCP3464R-E/ST

Analog To Digital Converters (ADC) Overview

The MCP3464R-E/ST is a quad-channel, 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) from Microchip Technology. It features a programmable data rate up to 153.6 ksps and analog gain ranging from 0.33x to 64x. The device operates with an analog supply voltage (AVDD) of 2.7V to 3.6V and a digital supply voltage (DVDD) of 1.8V to 3.6V. It includes an internal 2.4V voltage reference with 15 ppm/°C drift, an internal temperature sensor, and burnout current sources. The ADC provides 97.2 dB SINAD and -116 dBc THD at Gain = 1x and 4800 SPS. It utilizes a 20 MHz SPI-compatible interface and is housed in a 20-lead TSSOP package, specified over an extended temperature range of -40°C to +125°C.
