Microchip Technology MCP3551-E/SN
- Part Number:
- MCP3551-E/SN
- Manufacturer:
- Microchip Technology
- Ventron No:
- 3007937-MCP3551-E/SN
- Description:
- IC ADC 22BIT 2.7V 1CH SPI 8SOIC
- Datasheet:
- MCP3551-E/SN
Description
The MCP3550/1/3 are low-power, 22-bit Delta-Sigma Analog-to-Digital Converters (ADCs) with a wide input voltage range of 2.7V to 5.5V. They offer high accuracy with a total unadjusted error of less than 10 ppm, including 6 ppm Integral Non-Linearity (INL) error, 3 μV offset error, and less than 2 ppm full scale error. The devices feature low output noise of 2.5 μVRMS, resulting in an effective resolution of 21.9 bits (MCP3550/1).
Features
22-bit ADC in a compact 8-pin MSOP package
Automatic internal offset and gain calibration
Low output noise of 2.5 μVRMS
3 μV 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 a 3-wire SPI interface
Ultra-low conversion current (MCP3550/1):
100 μA typical (VDD = 2.7V)
120 μA typical (VDD = 5.0V)
Differential input with Vss to VDD common mode range
2.7V to 5.5V single-supply operation
Extended temperature range: -40°C to 125°C
Applications
Weigh scales
Direct temperature measurement
6-digit DVMs
Instrumentation
Data acquisition
Strain gauge measurement
