LTC2609/LTC2619/LTC2629

Quad 16-/14-/12-Bit

Rail-to-Rail DACs with

I

C Interface

Description

The LTC

®

2609/LTC2619/LTC2629 are quad 16-, 14- and 12-

bit, 2.7V to 5.5V rail-to-rail voltage output DACs in a 16-lead

SSOP package. 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 and load regulation in single-supply, volt-

age-output DACs.

The parts use a 2-wire, I

2

C 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

reset circuit. During power-up, the voltage outputs rise less

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.
