2606/LTC2616/LTC2626 are single 16-, 14- and
12-bit, 2.7V-to-5.5V rail-to-rail voltage output DACs in a
10-lead DFN package. They have built-in high performance
output buffers and are guaranteed monotonic.
10-lead DFN package. They have built-in high performance
output buffers and are guaranteed monotonic.
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, volt-
age-output DACs.

The parts use a 2-wire, I

C compatible serial interface. The
LTC2606/LTC2616/LTC2626 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.

of 400kHz). An asynchronous DAC update pin (LDAC) is
also included.
The LTC2606/LTC2616/LTC2626 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 LTC2606-1/LTC2616-1/
LTC2626-1 to mid-scale. The voltage outputs stay at mid-
scale until a valid write and update take place.
