DAC0854 Quad 8-Bit Voltage-Output Serial Digital To Analog Converter with Readback 5V 14mA IC DIP-20

DAC0854 Quad 8-Bit Voltage-Output Serial Digital To Analog Converter with Readback 5V 14mA IC DIP-20 The DAC0854 is a high-performance quad 8-bit voltage-output Digital-to-Analog Converter (DAC) featuring four independent DAC channels in a single package. It integrates output amplifiers, an internal precision voltage reference, and a serial MICROWIRE-compatible interface, significantly reducing external component count and PCB space requirements. The device operates from a single 5V supply and provides voltage outputs suitable for control, instrumentation, and signal generation applications. A key feature of the DAC0854 is its data readback capability, allowing a host microcontroller to verify that digital data has been correctly written into the DAC registers. The device uses double-buffered registers, enabling simultaneous updates of all four DAC outputs for synchronized multi-channel operation. With integrated reference circuitry, power-fail detection, and flexible serial communication, the DAC0854 is well suited for industrial, automotive, and embedded control systems.
