MAX538BCSA

MAX538BCSA Description

The MAX538BCSA is a 12-bit digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated, designed for precision voltage output applications. Housed in an 8-pin SOIC package, this surface-mount DAC operates with a single 5V analog and digital supply, making it suitable for low-power embedded systems. It features an SPI-compatible serial data interface, enabling easy integration with microcontrollers and digital signal processors. The device offers a settling time of 25µs (typical) and maintains ±1 LSB integral and differential nonlinearity (INL/DNL), ensuring high accuracy in voltage generation. Though now obsolete, it remains a reliable choice for legacy designs requiring stable, external-reference DAC performance.
