Description
Quad 16-/14-/12-Bit
Rail-to-Rail DACs with
I2C Interface
TheLTC2609/LTC2619/LTC2629arequad16-,14-and12-
bit,2.7Vto5.5Vrail-to-railvoltageoutputDACsina16-lead
SSOPpackage.Theyhavebuilt-inhighperformanceoutput
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, I2C compatible serial interface. The
LTC2609/LTC2619/LTC2629 operate in both the standard
mode (clock rate of 100kHz) and the fast mode (clock
rate of 400kHz).
The LTC2609/LTC2619/LTC2629 incorporate a power-on
resetcircuit.Duringpower-up,thevoltageoutputsriseless
than 10mV above zero-scale; after power-up, they stay at
zero-scale until a valid write and update take place. The
power-on reset circuit resets the LTC2609-1/LTC2619-1/
LTC2629-1 to mid-scale. The voltage outputs stay at mid-
scale until a valid write and update take place.
