FEATURES
· Eight Independent Channel 14-Bit DACs with
· Low Power 320 mW (typ.)
· Parallel Digital Data and Address Port
· Double Buffered Data Interface
· Readback of DAC Latches
· Zero Volt Output Preset (Data = 10 .. 00)

GENERAL DESCRIPTION
The MP7611 provides eight independent 14-bit resolution
Digital-to-Analog
amplifiers and a parallel digital address and data port.
Built using an advanced linear BiCMOS, these devices
offer rugged solutions that are latch-up free, and take
advantage of EXAR’s patented thin-film resistor process
which exhibits excellent long term stability and reliability.
A standard m-processor and TTL/CMOS compatible

and Parallel Data/Address mP Control Logic
14-bit input data port loads the data into the pre-selected
DACS.
This device can easily be interfaced to a data bus, and
digital readback of each channel is available.
Typical DAC matching for C grade versions is 1.5 LSB
across all codes. The output amplifier is capable of
sinking and sourcing 5mA, and the output voltage settles
to 12-bits in less than 30ms (typ.).
