DAC8222FS

The DAC8222FS is a dual 12-bit, double-buffered, CMOS digital-to-analog converter manufactured by Precision Monolithics. It features a 12-bit wide data port for direct loading of data, enabling faster throughput when interfacing with 12-bit or 16-bit processor systems. The device utilizes a common bus architecture, allowing for packaging in a narrow 24-pin SOIC package to save PCB space.

Key electrical specifications include a supply voltage range of 5V to 15V, a resolution of 12 bits, and a sample rate of 1 Msps. The operating temperature range is from -40°C to 85°C. The DAC8222FS offers two output channels and a typical supply current of 2.00 mA with a power dissipation of less than 0.5mW.

Controlled by WR and LDAC signals, the DAC registers can become transparent with a logic low input, allowing direct data flow to either DAC A or DAC B output. The double-buffered digital inputs permit simultaneous updates of both DACs. Its monolithic construction ensures excellent DAC-to-DAC matching and tracking across the full operating temperature range. This component is suitable for applications requiring precise analog output generation from digital signals.
