MCP3564-E/ST

MCP3564-E/ST Description

The MCP3564-E/ST from Microchip Technology is a high-precision 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) designed for demanding measurement applications. Housed in a compact 20-TSSOP package, it integrates a single ADC with SPI interface, supporting differential or single-ended inputs across 4 or 8 channels. Operating with dual supply voltages (analog: 2.7V–3.6V, digital: 1.8V–3.7V), it achieves a sampling rate of 153.6k samples per second, making it suitable for high-resolution data acquisition. The device is RoHS3 compliant, REACH unaffected, and rated for MSL 3 (168 hours) moisture sensitivity, ensuring reliability in industrial environments.
