廬

1657 is a complete single supply, rail-to-rail

voltage output, 16-bit digital-to-analog converter (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.

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.

The LTC1657 is similar to Linear Technology Corporation鈥檚

LTC1450 12-bit V

OUT

DAC 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.
