nn Narrow 28-Lead SSOP Package The LTCВ®1657/LTC1657L are complete single supply, railto-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. nn 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 …
