Family

The LTC

1655/LTC1655L are rail-to-rail voltage output,

16-bit digital-to-analog converters in an SO-8 package.

They include an output buffer and a reference. The 3-wire

serial interface is compatible with SPI/QSPI and

MICROWIRE

protocols. The CLK input has a Schmitt

trigger that allows direct optocoupler interface.

The LTC1655 has an onboard 2.048V reference that can be

overdriven to a higher voltage. The output swings from 0V

to 4.096V when using the internal reference. The typical

power dissipation is 3.0mW on a single 5V supply.

The LTC1655L has an onboard 1.25V reference that can be

overdriven to a higher voltage. The output swings from 0V

to 2.5V when using the internal reference. The typical

power dissipation is 1.8mW on a single 3V supply.

The LTC1655/LTC1655L are pin compatible with Linear

Technology’s 12-bit V

OUT

DAC family, allowing an easy

upgrade path. They are the only buffered 16-bit DACs in

an SO-8 package and they include an onboard reference

for standalone performance.
