MCP355X 22-Bit Delta-Sigma A/D Converters

Microchip's low-noise analog-to-digital converters (ADCs) for sensor measurement applications

Image of Microchip MCP355X 22-bit Delta-Sigma A/D ConvertersThe MCP355X series of devices from Microchip Technology are 2.7 V to 5.5 V low-power, 22-bit delta-sigma A/D converters. The MCP355X devices provide high accuracy and low noise performance for applications where sensor measurements, such as pressure, temperature, and humidity, are performed. The devices offer output noise as low as 2.5 µVRMS with a total unadjusted error of less than 10 ppm. The family exhibits less than 6 ppm integral nonlinearity (INL) error, 3 µV offset error, and 2 ppm full scale error. Minimal external components are required for high accuracy applications due to the internal oscillator and high oversampling rate. The fully differential analog inputs make it compatible with a wide variety of sensor and measurement applications. The MCP355X devices operate from -40°C to +125°C and are available in the space-saving 8-pin MSOP and SOIC packages.
