Description

The Microchip Technology Inc. MCP3550/1/3 devices

are 2.7V to 5.5V low-power, 22-bit Delta-Sigma

Analog-to-Digital Converters

(ADCs). The devices offer

output noise as low as 2.5 µVRMS, with a total

unadjusted error of 10 ppm. The family exhibits 6 ppm

Integral Non-Linearity (INL) error, 3 µV offset error and

less than 2 ppm full scale error. The MCP3550/1/3

devices provide high accuracy and low noise

performance

for

applications

where

sensor

measurements (such as pressure, temperature and

humidity) are performed. With the internal oscillator

and high oversampling rate, minimal external

components

are

required

for

high-accuracy

applications.

This product line has fully differential analog inputs,

making it compatible with a wide variety of sensor,

industrial control or process control applications.

The MCP3550/1/3 devices operate from -40°C to

+125°C and are available in the space-saving 8-pin

MSOP and SOIC packages.
