DESCRIPTION
Octal 16-/14-/12-Bit
Rail-to Rail DACs in 16-Lead SSOP
The LTC2605/LTC2615/LTC2625 are octal 16-, 14- and
12-bit, 2.7V to 5.5V rail-to-rail voltage-output DACs
in 16-lead narrow SSOP packages. They have built-in
high performance output buffers and are guaranteed
monotonic.
These parts establish new board-density benchmarks
for 16-/14-bit DACs and advance performance standards
for output drive, crosstalk and load regulation in single
supply, voltage-output multiples.
The parts use the 2-wire I2C compatible serial interface. The
LTC2605/LTC2615/LTC2625 operate in both the standard
mode (maximum clock rate of 100kHz) and the fast mode
(maximum clock rate of 400kHz).
The LTC2605/LTC2615/LTC2625 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 LTC2605-1/\LTC2615-1/
LTC2625-1 to mid-scale. The voltage output stays at mid-
scale until a valid write and update takes place.
