DESCRIPTION
The
LTC
®
1657/LTC1657L
are complete single supply, rail-
to-rail voltage output, 16-bit digital-to-analog converters
(DAC) in a 28-pin SSOP package. They include a rail-to-rail
output buffer amplifier, an internal reference and a double
buffered parallel digital interface.
The LTC1657/LTC1657L have separate reference input pins
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 operates
from a 4.5V to 5.5V supply and has an onboard 2.048V
reference. The LTC1657L operates from a 2.7V to 5.5V
supply and has an onboard 1.25V reference.
The LTC1657/LTC1657L are similar to Linear Technology
Corporation’s LTC1450/LTC1450L 12-bit V
OUT
DAC family,
allowing an upgrade path. They are the only buffered 16-bit
parallel DACs in a 28-lead SSOP package and include an
onboard reference for stand alone performance.
