5.5 V power supply, making it suited to battery-powered and
other applications.
As a result of being manufactured on a CMOS submicron process,
this part offers excellent four-quadrant multiplication character-
istics, with large signal multiplying bandwidths of 10 MHz.

precision amplifier.
This DAC uses a double-buffered, 3-wire serial interface that is
compatible with SPI, QSPI™, MICROWIRE®, and most DSP
interface standards. In addition, a serial data out pin (SDO)
allows daisy-chaining when multiple packages are used. Data
readback allows the user to read the contents of the DAC register
via the SDO pin. On power-up, the internal shift register and
latches are filled with 0s, and the DAC outputs are at zero scale.
