Key Features

  • 22-bit resolution with 0.0006% maximum linearity error for ultra-precise measurement applications
  • Delta-sigma architecture with ±2.5 V differential input range suits bridge sensor and precision voltage measurement
  • Low-power SPI-compatible interface in compact 8-pin MSOP package for space- and power-constrained designs

Applications

The MCP3550-60E/MS is ideal for precision industrial weighing systems, strain gauge bridges, and high-accuracy temperature measurement circuits that demand 22-bit resolution with minimal linearity error. Its delta-sigma architecture provides inherent anti-aliasing and noise shaping, simplifying the analog front end compared to successive-approximation ADCs. The low-power SPI interface and compact MSOP-8 package make it well-suited for portable data loggers and battery-operated field instruments.

Frequently Asked Questions

What resolution does the MCP3550-60E/MS offer, and how does it benefit precision sensor measurement?

The MCP3550-60E/MS provides 22-bit resolution with a maximum linearity error of only 0.0006%. At a ±2.5 V input range this equates to a minimum resolvable voltage step of approximately 1.2 µV, enabling accurate measurement of small differential signals from strain gauges, thermocouples, and Wheatstone bridge sensors without requiring external signal amplification.

What is the conversion time of the MCP3550-60E/MS, and how does it affect sampling rate in data logging systems?

The MCP3550-60E/MS has a maximum conversion time of approximately 67.3 ms, yielding a maximum sample rate near 15 samples per second. While this limits it to slow measurement applications, the delta-sigma architecture's oversampling and decimation filtering within that window delivers 22-bit noise-free codes without additional anti-aliasing filters, reducing BOM cost in precision data logging instruments.

What interface and package does the MCP3550-60E/MS use, and how does it simplify integration into microcontroller-based designs?

The MCP3550-60E/MS uses an SPI-compatible serial interface and comes in an 8-pin MSOP package with a footprint of approximately 3 mm × 3 mm. The SPI bus allows direct connection to any microcontroller with a hardware SPI peripheral, and the 8-pin MSOP requires only a handful of passive decoupling components, allowing complete 22-bit ADC front ends to occupy less than 1 cm² of PCB area.
