DAC088S085
8-Bit Micro Power OCTAL Digital-to-Analog Converter with
Rail-to-Rail Outputs
General 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 +2.7V to +5.5V supply and con-
sumes 1.95 mW at 3V and 4.85 mW at 5V. The DAC088S085
is packaged in a 16-lead LLP package and a 16-lead TSSOP
package. The LLP package makes the DAC088S085 the
smallest OCTAL DAC in its class. The on-chip output ampli-
fiers 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 2.7V to 3.6V range.
The serial interface is compatible with standard SPI™, QSPI,
MICROWIRE and DSP interfaces. The DAC088S085 also of-
fers daisy chain operation where an unlimited number of
DAC088S085s can be updated simultaneously using a single
serial interface.
There are two references for the DAC088S085. One refer-
ence input serves channels A through D while the other
reference serves channels E through H. Each reference can
be set independently between 0.5V and V
A
, providing the
widest possible output dynamic range. The DAC088S085 has
a 16-bit input shift register that controls the mode of operation,
the power-down condition, and the DAC channels' register/
output value. All eight DAC outputs can be updated simulta-
neously or individually.
A power-on reset circuit ensures that the DAC outputs power
up to zero volts and remain there until there is a valid write to
the device. The power-down feature of the DAC088S085 al-
lows each DAC to be independently powered with three dif-
ferent termination options. With all the DAC channels
powered down, power consumption reduces to less than 0.3
µW at 3V and less than 1 µW at 5V. The low power consump-
tion and small packages of the DAC088S085 make it an
excellent choice for use in battery operated equipment.
The DAC088S085 is one of a family of pin compatible DACs,
including the 10-bit DAC108S085 and the 12-bit
DAC128S085. All three parts are offered with the same
pinout, allowing system designers to select a resolution ap-
propriate for their application without redesigning their printed
circuit board. The DAC088S085 operates over the extended
industrial temperature range of −40°C to +125°C.
