MCP3903-I/SS Description

Short technical summary and product information.

The MCP3903-I/SS from Microchip Technology is a versatile 6-channel Analog Front End (AFE) designed for applications requiring precise signal acquisition. This device features 24-bit resolution Delta-Sigma Analog-to-Digital Converters (ADCs) with a proprietary multi-bit architecture.

Key electrical specifications include independent analog and digital power supplies, with analog voltage ranging from 4.5V to 5.5V and digital voltage from 2.7V to 3.6V. It offers high performance with 91 dB SINAD, -100 dBc THD, and 102 dB SFDR per channel. The device supports programmable data rates up to 64 kSPS and includes an ultra-low-power shutdown mode consuming less than 2 μA.

Designed for energy metering, power measurement, and portable instrumentation, the MCP3903-I/SS is available in a compact 28-lead SSOP package. It supports a wide operating temperature range from -40°C to +125°C, making it suitable for demanding environments. The high-speed 10 MHz SPI interface simplifies communication with microcontrollers.
