Digital to Analog Converters

MCP4728A0-E/UN Description

The MCP4728A0-E/UN is a high-performance, 12-bit Digital-to-Analog Converter (DAC) from Microchip Technology, designed for applications requiring precise analog output control. This device features four independent DACs, each capable of converting digital input signals into analog voltage outputs. The MCP4728A0-E/UN operates within a wide supply voltage range of 2.7V to 5.5V for both analog and digital supplies, ensuring compatibility with various power sources and systems. The device employs a String DAC architecture, which provides excellent linearity and accuracy, with an Integral Non-Linearity (INL) and Differential Non-Linearity (DNL) of ±2 LSB and ±0.2 LSB, respectively. The fast settling time of 6µs (typical) ensures rapid response to input changes, making it suitable for dynamic applications. The MCP4728A0-E/UN also features an internal reference, which simplifies design and reduces the need for external components. The device is available in a surface-mount 10-MSOP package, making it ideal for compact and space-constrained designs. The MCP4728A0-E/UN is REACH unaffected and RoHS3 compliant, ensuring environmental and regulatory compliance.
