FEATURES
DESCRIPTION
The DAC088S085 is a full-featured, general purpose

• Ensured Monotonicity
OCTAL 8-bit voltage-output digital-to-analog
• Low Power Operation
converter (DAC) that can operate from a single +2.7V
• Rail-to-Rail Voltage Output
to +5.5V supply and consumes 1.95 mW at 3V and
4.85 mW at 5V. The DAC088S085 is packaged in a
• Daisy Chain Capability
16-lead WQFN package and a 16-lead TSSOP
• Power-on Reset to 0V
package. The WQFN package makes the
• Simultaneous Output Updating
DAC088S085 the smallest OCTAL DAC in its class.
The on-chip output amplifiers allow rail-to-rail output
• Individual Channel Power Down Capability
swing and the three wire serial interface operates at
• Wide power supply range (+2.7V to +5.5V)
clock rates up to 40 MHz over the entire supply
• Dual Reference Voltages with range of 0.5V to
voltage range. Competitive devices are limited to 25
V
A MHz clock rates at supply voltages in the 2.7V to
3.6V range. The serial interface is compatible with
• Operating Temperature Range of −40°C to
standard SPI™, QSPI, MICROWIRE and DSP
+125°C
interfaces. The DAC088S085 also offers daisy chain

a single serial interface.
• Battery-Powered Instruments
There are two references for the DAC088S085. One

the other reference serves channels E through H.
• Programmable Voltage & Current Sources
Each reference can be set independently between

register/output value. All eight DAC outputs can be
updated simultaneously or individually.
KEY SPECIFICATIONS
A power-on reset circuit ensures that the DAC

there is a valid write to the device. The power-down
feature of the DAC088S085 allows each DAC to be

• Zero Code Error: +15 mV (max)
powered down, power consumption reduces to less
than 0.3 µW at 3V and less than 1 µW at 5V. The low
