Overview

The MCP3204-CI/P is a 12-bit Analog-to-Digital Converter (ADC) that combines high performance with low power consumption in a classic 14-pin PDIP package. It features four single-ended input channels or two pseudo-differential pairs, utilizing a Successive Approximation Register (SAR) architecture to achieve a 100ksps sampling rate. Operating over a voltage range of 2.7V to 5.5V, it communicates via a standard SPI serial interface, making it easy to integrate with a wide variety of microcontrollers.

Why Choose This Part

The 14-PDIP package is highly advantageous for through-hole prototyping and breadboarding without requiring surface-mount adapters. Its low power consumption of 0.4mA at 5V, combined with a 100ksps sample rate, provides an excellent balance of speed and efficiency for mid-range sensing applications.

Applications

Sensor Signal Conditioning
Ideal for converting analog signals from pressure, temperature, or light sensors into digital data for processing.
Battery Monitoring
The ultra-low standby current of 0.5uA makes it suitable for power-sensitive, battery-operated remote monitoring systems.
Industrial Process Control
Provides reliable 12-bit resolution for monitoring analog loops and instrumentation in factory environments.
Data Acquisition Systems
Serves as a multi-channel front-end for logging data from multiple analog sources simultaneously.
