The LTC®2602/LTC2612/LTC2622 are dual 16-,14- and
12-bit, 2.5V-to-5.5V rail-to-rail voltage-output DACs, in a
tiny 8-lead MSOP package. They have built-in high per-
formance output buffers and are guaranteed monotonic.
These parts establish advanced performance standards
for output drive, crosstalk and load regulation in single-
supply, voltage output multiples.
The parts use a simple SPI/MICROWIRE™ compatible
3-wire serial interface which can be operated at clock
rates up to 50MHz.
The LTC2602/LTC2612/LTC2622 incorporate a power-
on reset circuit. During power-up, the voltage outputs
rise less than 10mV above zero scale, and after power-
up, they stay at zero scale until a valid write and update
