An internal feedback resistor (RFB) provides temperature • Midscale or Zero-Scale Reset tracking for the full-scale output when combined with • Four Separate 4Q Multiplying Reference an external I-to-V precision amplifier. Inputs A doubled buffered serial data interface offers • Reference Bandwidth: 10 MHz high-speed, 3-wire, SPI and microcontroller • Reference Dynamics: –105 dB THD compatible inputs using serial data in (SDI), clock • SPI™-Compatible 3-Wire Interface: (CLK), and a chip-select (CS). In addition, a serial 50 MHz data out pin (SDO) allows for daisy-chaining when • Double Buffered Registers Enable multiple packages are used. A common level-sensitive load DAC strobe (LDAC) input allows • Simultaneous Multichannel Change simultaneous update of all DAC outputs from • Internal Power-On Reset previously loaded input registers. Additionally, an • Industry-Standard Pin Configuration 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 • Automatic Test Equipment MSB = 1. • Instrumentation • Digitally-Controlled Calibration The DAC8814 is available in an SSOP package.
