LTC1657

Parallel 16-Bit Rail-to-Rail

Micropower DAC

DESCRIPTIO

FEATURES

The LTC^®1657 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 2.048V reference and

a double buffered parallel digital interface.

■

16-Bit Monotonic Over Temperature

■

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

■

5V Single Supply Operation

■

I_CC: 650µA Typ

■

Maximum DNL Error: ±1LSB

■

Settling Time: 20µs to ±1LSB

The LTC1657 operates from a 4.5V 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 Zero Volts

■

Asynchronous CLR Pin

■

Output Buffer Configurable for Gain of 1 or 2

■

Parallel 16-Bit or 2-Byte Double Buffered Interface

TheLTC1657issimilartoLinearTechnologyCorporation’s

LTC1450 12-bit V_OUTDAC family allowing an upgrade

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.
