LTC2605/LTC2615/LTC2625

Octal 16-/14-/12-Bit

Rail-to-Rail DACs in 16-Lead SSOP

DESCRIPTIO

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 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 midscale. The voltage output

stays at midscale until a valid write and update

takes place.
