DAC8426FS

DAC8426FS Description

The DAC8426FS from Analog Devices Inc. is an 8-bit, quad-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in a 20-pin SOIC package, this surface-mount device operates with dual power supplies (13.5V to 16.5V for both analog and digital domains), ensuring robust performance in industrial and instrumentation systems. Featuring a parallel data interface, the DAC8426FS delivers a fast 3µs settling time (typical) and maintains excellent linearity with ±1 LSB INL/DNL (max). Its internal reference simplifies design integration, while its 4-channel output enables multi-axis control in complex systems.
