MCP3562-E/ST

MCP3562-E/ST Description

The MCP3562-E/ST from Microchip Technology is a high-performance, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) designed for precision measurement applications. Housed in a 20-pin TSSOP package, this dual-channel ADC integrates advanced features such as a programmable gain amplifier (PGA), an internal oscillator, and a temperature sensor, making it ideal for systems requiring high-resolution signal acquisition. It supports both differential and single-ended inputs, with configurable input channels (2 or 4), providing flexibility for diverse sensor interfaces. The device operates with dual supply voltages: 2.7V–3.6V (analog) and 1.8V–3.7V (digital), ensuring compatibility with low-power and mixed-voltage systems. With a sampling rate of up to 153.6 kSPS, it delivers high-speed, low-noise performance for demanding applications.
