DESCRIPTIO
The LTC®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 perfor-
mance 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,
voltage-output DACs.
The parts use a 2-wire, I2C 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.
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 midscale. The voltage outputs stay at
midscale until a valid write and update take place.
