GENERAL DESCRIPTION
The MP7612 provides eight independent 12-bit resolution
Digital-to-Analog Converters with voltage output amplifiers and
a 3-wire standard serial digital address and data port.
Typical DAC matching for B grade versions is 0.7 LSB across
all codes. Accuracy of +0.75 LSB for DNL and +1 LSB for INL is
also achieved for B grades. The output amplifier is capable of
sinking and sourcing 5mA, and the output voltage settles to
12-bits in less than 30
μ
s (typ.).
The MP7612 is equipped with a serial data (3-wire standard)
μ
-processor logic interface to reduce pin count, package size,
and board space.
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 excel-
lent long term stability and reliability.
