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 VRMS, with a total
unadjusted error of 10 ppm. The family exhibits 6 ppm
Integral Non-Linearity (INL) error, 3 V 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.
