The LTC®2605/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- and 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 midscale. The voltage output
stays at midscale until a valid write and update
takes place.
