2607/LTC2617/LTC2627 are dual 16-, 14- and
12-bit, 2.7V to 5.5V rail-to-rail voltage output DACs in a
12-lead DFN package. They have built-in high performance
output buffers and are guaranteed monotonic.
These parts establish new board-density benchmarks for
These parts establish new board-density benchmarks for
16- and 14-bit DACs and advance performance standards
for output drive and load regulation in single-supply,
voltage-output DACs.
The parts use a 2-wire, I

C compatible serial interface. The
LTC2607/LTC2617/LTC2627 operate in both the standard
mode (clock rate of 100kHz) and the fast mode (clock rate
of 400kHz). An asynchronous DAC update pin (LDAC) is
also included.
The LTC2607/LTC2617/LTC2627 incorporate a power-on
The LTC2607/LTC2617/LTC2627 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 take place. The
power-on reset circuit resets the LTC2607-1/LTC2617-1/
LTC2627-1 to mid-scale. The voltage outputs stay at mid-
scale until a valid write and update takes place.
