An internal feedback resistor (RFB) provides temperature tracking • Midscale or Zero-Scale Reset for the full-scale output when combined with an • Four Separate 4-Quadrant Multiplying external I-to-V precision amplifier. Reference Inputs A doubled buffered serial data interface offers • Reference Bandwidth: 10 MHz high-speed, 3-wire, SPI and microcontroller compat- • Reference Dynamics: -105 dB THD ible inputs using serial data in (SDI), clock (CLK), and • 50-MHz SPI™-Compatible 3-Wire Interface a chip select (CS). In addition, a serial data out pin • Double Buffered Registers Enable (SDO) allows for daisy chaining when multiple pack- ages are used. A common level-sensitive load DAC • Simultaneous Multichannel Update strobe (LDAC) input allows simultaneous update of all • Internal Power On Reset DAC outputs from previously loaded input registers. • Compact SSOP-28 Package Additionally, an internal power on reset forces the output voltage to zero at system turn on. An MSB pin • Industry-Standard Pin Configuration allows system reset assertion (RS) to force all regis- ters to zero code when MSB = 0, or to half-scale code when MSB = 1. • Automatic Test Equipment The DAC8803 is packaged in a SSOP package. • Instrumentation • Digitally Controlled Calibration Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
