MCP3551-E/SN

MCP3551-E/SN is a low-power, single-channel 22bit delta-sigma ADC. It provides 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 analogue inputs, making it compatible with a wide variety of sensor, industrial control, or process control applications. The application includes weighing scales, direct temperature measurement, 6-digit DVMs, instrumentation, data acquisition, and strain gauge measurement.
