Microchip | MCP3422A0-E/SN

Microchip Technology is a leading innovator and supplier of high performance and high quality microcontrollers and analog semiconductor. Microchip offers a broad spectrum of analog products with a focus on power management, thermal management, linear and mixed-signal solutions.

The MCP3422 is a two channel low-noise, high accuracy delta-sigma A/D converter with differential inputs and up to 18 bits of resolution. The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially. The device uses a two-wire I2C™ compatible serial interface and operates from a single power supply ranging from 2.7V to 5.5V.

The MCP3422 device performs conversions at rates of 3.75, 15, 60 or 240 samples per second depending on user controllable configuration bit settings using the two-wire I2C Compatible compatible serial interface. This device has an onboard programmable gain amplifier (PGA). User can select the PGA gain of x1, x2, x4, or x8 before the analog-to-digital conversion takes place. This allows the MCP3422 device to convert a smaller input signal with high resolution.

The MCP3422 device can be used for various high accuracy analog-to-digital data conversion applications where ease of use, low power consumption and small footprint are major considerations.
