APPLICATIO
S
U
The LTC
1657L 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 1.25V reference and a
double buffered parallel digital interface.
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.
The LTC1657L is similar to Linear Technology Corporation’s
LTC1450 12-bit V
OUT
DAC 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.
