MCP3208-BI/P

MCP3208-BI/P Description

The MCP3208-BI/P is a high-performance 12-bit SAR (Successive Approximation Register) analog-to-digital converter (ADC) from Microchip Technology. Designed for precision measurement applications, it features 8 single-ended or 4 pseudo-differential input channels, offering flexibility in signal acquisition. The device operates with a 2.7V to 5.5V dual supply range (analog and digital), making it suitable for both low-power and standard voltage systems. Its SPI-compatible serial interface ensures seamless integration with microcontrollers and digital systems. Packaged in a 16-pin PDIP (Plastic Dual In-line Package), the MCP3208-BI/P is ideal for through-hole mounting in industrial and embedded designs.
