LTC2657

Octal I C 16-/12-Bit

Rail-to-Rail DACs with

10ppm/°C Max Reference

DESCRIPTION

FEATURES

The LTC^®2657 is a family of octal I C 16-/12-Bit Rail-to-

Integrated Reference 10ppm/°C Max

Maximum INL Error: ±±LꢀS

Rail DACs with Integrated 10ppm/°C Max Reference. The

DACs have built-in high performance, rail-to-rail, output

buffersandareguaranteedmonotonic. TheLTC2657-Lhas

operatesfromasingle2.7Vto5.5Vsupply. TheLTC2657-H

andoperatesfroma4.5Vto5.5Vsupply.EachDACcanalso

operatewithanexternalreference, whichsetsthefull-scale

output to 2 times the external reference voltage.

Guaranteed Monotonic Over Temperature

2.7V to 5.5V Supply Range (LTC2657-L)

Integrated Reference Buffers

Ultralow Crosstalk between DACs(0.8nV•s)

Power-On-Reset to Zero-Scale/Mid-Scale

400kHz I C Interface

Tiny 20-Lead 4mm × 5mm QFN and 20-Lead

Thermally enhanced TSSOP packages

The parts use a 2-wire I C compatible serial interface. The

LTC2657 operates in both the standard mode (maximum

clock rate of 100kHz) and the fast mode (maximum clock

rateof400kHz).TheLTC2657incorporatesapower-onreset
