Micropower Quad

10-Bit DAC

Features

Description

Tiny: 4 DACs in the Board Space of an SO-8

TheLTC^®1664integratesfouraccurate,seriallyaddressable

10-bit digital-to-analog converters (DACs) in a tiny 16-pin

narrowSSOPpackage.EachbufferedDACdrawsjust59µA

total supply current, yet is capable of supplying DC output

currents in excess of 5mA and reliably driving capacitive

loads of up to 1000pF. Sleep mode further reduces total

supply current to 1µA.

Micropower: 59µA per DAC Plus

1µA Sleep Mode for Extended Battery Life

Wide 2.7V to 5.5V Supply Range

Rail-to-Rail Voltage Outputs Drive 1000pF

Reference Range Includes Supply for Ratiometric

0V to V Output

Reference Input Impedance is Code-Independent

—Eliminates External Reference Buffer

Individually Addressable DACs

Linear Technology’s proprietary, inherently monotonic

voltage interpolation architecture provides excellent lin-

earity while allowing for an exceptionally small external

form factor.

Differential Nonlinearity: ≤ 0.75LSꢀ Max

Pin-Compatible Octal Version Available (LTC1660)

Ultralow supply current, power-saving sleep mode and

extremely compact size make the LTC1664 ideal for

battery-powered applications, while its ease of use, high

performance and wide supply range make it an excellent

choice as a general-purpose converter.
