Description

The DAC8814 is a quad, 16-bit, current-output digi- tal-to-analog converter (DAC) designed to operate from a single +2.7 V to 5.0 V supply.

The applied external reference input voltage V_REF determines the full-scale output current. An internal feedback resistor (R_FB) provides temperature tracking for the full-scale output when combined with an external I-to-V precision amplifier.

A doubled buffered serial data interface offers high-speed, 3-wire, SPI and microcontroller compatible inputs using serial data in (SDI), clock (CLK), and a chip-select (CS). In addition, a serial data out pin (SDO) allows for daisy-chaining when multiple pack- ages are used. A common level-sensitive load DAC strobe (LDAC) input allows simultaneous update of all DAC outputs from previously loaded input registers. Additionally, an internal power on reset forces the output voltage to zero at system turn on. An MSB pin allows system reset assertion (RS) to force all registers to zero code when MSB = 0, or to half-scale code when MSB = 1.

The DAC8814 is available in an SSOP package.
