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’s 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.).
