MCHPMCP47FEB21A0T-E/ST
Overview
The MCP47FEB21A0T-E/ST is a single-channel, 12-bit voltage output Digital-to-Analog Converter (DAC) featuring integrated non-volatile EEPROM and an I2C interface. It provides a buffered voltage output with flexible reference options, including external, internal, or the supply voltage (VDD).
Why Choose This Part
The integrated 64-byte EEPROM allows for the storage of DAC registers and configuration settings, which are automatically restored at power-up. It offers high precision with a +/-1.5 LSB maximum INL and includes a buffered output that simplifies circuit design by reducing the need for external op-amps.
Applications
Key Specifications
Getting Started
To evaluate this DAC, connect the I2C pins (SCL and SDA) to a microcontroller like a PIC or AVR and pull up the lines to VDD (2.7V to 5.5V). Use the A0 pin to configure the hardware address and refer to Microchip's MCC (MHC) or standard I2C libraries to write to the volatile or non-volatile registers.
