Low-Power, Single-Channel 22-Bit Delta-Sigma ADCs
Features: Description: 22-Bit ADC in Small 8-pin MSOP Package with
Automatic Internal Offset and Gain Calibration Low-Output Noise of 2.5 ВµVRMS with Effective
Resolution of 21.9 Bits (MCP3550/1) 3 ВµV Typical Offset Error 2 ppm Typical Full Scale Error 6 ppm Maximum INL Error Total Unadjusted Error Less Than 10 ppm No Digital Filter Settling Time, Single-Command
Conversions through 3-wire SPI Interface Ultra-Low Conversion Current (MCP3550/1):
-100 ВµA Typical (VDD = 2.7V)
-120 ВµA Typical (VDD = 5.0V) Differential Input with VSS to VDD Common Mode
Range 2.7V to 5.5V Single-Supply Operation Extended Temperature Range:
-40В°C to +125В°C The Microchip Technology Inc. MCP3550/1/3 devices
are 2.7V to 5.5V low-power, 22-bit Delta-Sigma
Analog-to-Digital Converters пЂЁADCs). The devices offer
output noise as low as 2.5 ВµVRMS, with a total
unadjusted error of 10 ppm. The family exhibits 6 ppm
Integral Non-Linearity (INL) error, 3 ВµV offset error and
less than 2 ppm full scale error. The MCP3550/1/3
devices provide high accuracy and low noise
