MCP3426A0-E/SN

MCP3426A0-E/SN Description

The MCP3426A0-E/SN from Microchip Technology is a high-precision, 16-bit delta-sigma analog-to-digital converter (ADC) designed for low-power, high-accuracy measurement applications. Housed in an 8-SOIC package, this ADC integrates a single-channel differential input with an I2C interface, making it ideal for space-constrained designs. Operating across a 2.7V to 5.5V supply range, it ensures compatibility with both 3.3V and 5V systems. The device features an internal reference and a programmable gain amplifier (PGA) with selectable gains (1x, 2x, 4x, 8x), enabling precise signal conditioning for low-voltage sensors. With a 15 SPS sampling rate, it balances resolution and speed for applications requiring high accuracy without excessive bandwidth demands.
