LTC2609/LTC2619/LTC2629

Quad 16-/14-/12-Bit

Rail-to-Rail DACs with

I C Interface

Features

Description

TheLTC^®2609/LTC2619/LTC2629arequad16-,14-and12-

bit,2.7Vto5.5Vrail-to-railvoltageoutputDACsina16-lead

SSOPpackage.Theyhavebuilt-inhighperformanceoutput

buffers and are guaranteed monotonic.

Smallest Pin-Compatible Quad DACs:

LTC2609: 16 Bits

LTC2619: 14 Bits

LTC2629: 12 Bits

Guaranteed Monotonic Over Temperature

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.

LTC2609/LTC2619/LTC2629: Power-On Reset to

Zero-Scale

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

resetcircuit.Duringpower-up,thevoltageoutputsriseless

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.
