MCP4921T-E/MS

MCP4921T-E/MS Description

The MCP4921T-E/MS from Microchip Technology is a high-performance 12-bit Digital-to-Analog Converter (DAC) designed for precision analog output applications. Housed in a compact 8-MSOP package, this single-channel DAC features an SPI interface for seamless integration with microcontrollers and digital systems. With a ±4 LSB INL (Integral Non-Linearity) and ±0.25 LSB DNL (Differential Non-Linearity), it delivers excellent linearity and accuracy. The device operates over a wide analog/digital supply range (2.7V–5.5V), making it suitable for both low-power and standard voltage applications. Its 4.5µs settling time ensures rapid response in dynamic systems, while the external reference allows flexibility in output voltage scaling.
