MAX533BEEE

MAX533BEEE Description

The MAX533BEEE is an 8-bit, quad-channel digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated, designed for precision voltage output applications. Housed in a 16-QSOP package, this surface-mount device operates with 2.7V to 3.6V analog and digital supplies, making it suitable for low-power embedded systems. It features an SPI interface for seamless communication with microcontrollers and offers a fast 6µs settling time (typical), ensuring rapid response in dynamic applications. With ±2 LSB INL and ±1 LSB DNL (max), it delivers reliable linearity for moderate-resolution requirements. The external reference design allows flexibility in setting the output range, while its string DAC architecture ensures stable performance.
