GENERAL DESCRIPTION
The MP7611 provides eight independent 14-bit resolution
Digital-to-Analog Converters with voltage output
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鈥檚 patented thin-film resistor process
which exhibits excellent long term stability and reliability.
A standard
m-processor
and TTL/CMOS compatible
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.).
