3 Description
The DAC088S085 is a full-featured, general-purpose,
OCTAL, 8-bit, voltage-output, digital-to-analog
converter (DAC) that can operate from a single 2.7 V
to 5.5 V supply and consumes 1.95 mW at 3 V and
4.85 mW at 5 V. The DAC088S085 is packaged in a
16-pin WQFN package and a 16-pin TSSOP
package. The WQFN package makes the
DAC088S085 the smallest OCTAL DAC in its class.
The on-chip output amplifiers allow rail-to-rail output
swing and the three-wire serial interface operates at
clock rates up to 40 MHz over the entire supply
voltage range. Competitive devices are limited to
25‑MHz clock rates at supply voltages in the range of
2.7 V to 3.6 V. The serial interface is compatible with
standard SPI™, QSPI, MICROWIRE, and DSP
interfaces. The DAC088S085 also offers daisy chain
operation where an unlimited number of devices can
be updated simultaneously using a single serial
interface.
