Final Electrical Specifications

LTC1657L

Parallel 16-Bit Rail-to-Rail

Micropower DAC

April 2000

DESCRIPTION

FEATURES

The LTC^®1657L is a complete single supply, rail-to-rail

voltageoutput, 16-bitdigital-to-analogconverter(DAC)in

a 28-pin SSOP or PDIP package. It includes a rail-to-rail

output buffer amplifier, an internal 1.25V reference and a

double buffered parallel digital interface.

■

16-Bit Monotonic Over Temperature

■

3V Single Supply Operation

■

Deglitched Rail-to-Rail Voltage Output: 8nV • s

■

I_CC: 650µA Typ

■

Maximum DNL Error: ±1LSB

■

Settling Time: 20µs to ±1LSB

The LTC1657L operates from a 2.7V to 5.5V supply. It has

a separate reference input pin that can be driven by an

external reference. The full-scale output can be 1 or 2

times the reference voltage depending on how the X1/X2

pin is connected.

■

Internal or External Reference

■

Internal Power-On Reset to 0V

■

Asynchronous CLR Pin

■

Output Buffer Configurable for Gain of 1 or 2

■

Parallel 16-Bit or 2-Byte Double Buffered Interface

■

TheLTC1657LissimilartoLinearTechnologyCorporation’s

LTC1450 12-bit V_OUTDAC family allowing an easy up-

grade path. It is the only buffered 16-bit parallel DAC in a

28-lead SSOP package and includes an onboard reference

for stand alone performance.

Narrow 28-Lead SSOP Package

5V Version Available (LTC1657)
