GENERAL DESCRIPTION
The MP7610 provides eight independent 14-bit resolution
Digital-to-Analog Converters with voltage output
amplifiers and a 3-wire standard serial digital address and
data port.
The output amplifier is capable of sinking and sourcing
5mA, and the output voltage settles to 12-bits in less than
30ms (typ.).
The MP7610 is equipped with a serial data (3-wire
standard) m-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 excellent long term stability and reliability.
