MCHPMCP4725A3T-E/CH
Overview
The MCP4725 is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) with non-volatile memory (EEPROM). It communicates via a two-wire I2C-compatible serial interface and operates from a single 2.7V to 5.5V supply. The integrated EEPROM allows the device to store DAC register settings, ensuring the output powers up to a known state even after a power cycle.
Why Choose This Part
The inclusion of on-board EEPROM simplifies system design by retaining configuration through power losses without requiring constant microcontroller intervention. Its small SOT-23-6 package and low power consumption make it ideal for space-constrained and power-sensitive applications.
Applications
Getting Started
Interface the device with any I2C-capable microcontroller like an Arduino or PIC. Ensure the A0 address bit is tied to VDD or VSS to match the target I2C address, and use pull-up resistors on the SDA and SCL lines. For rapid prototyping, many third-party breakout boards are available to adapt the SOT-23 package to breadboard-friendly headers.
