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 or PDIP 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 Technol-
ogy Corporation’s LTC1450/LTC1450L 12-bit VOUT 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.
