LTC2605/LTC2615/LTC2625

Octal 16-/14-/12-Bit

Rail-to Rail DACs in 16-Lead SSOP

FEATURES

DESCRIPTION

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-/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 I

C 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.
