APPLICATIU
FEATURES
DESCRIPTIOU
The LTC
1666/LTC1667/LTC1668 are 12-/14-/16-bit,
50Msps differential current output DACs implemented on
a high performance BiCMOS process with laser trimmed,
thin-film resistors. The combination of a novel current-
steering architecture and a high performance process
produces DACs with exceptional AC and DC performance.
The LTC1668 is the first 16-bit DAC in the marketplace to
exhibit an SFDR (spurious free dynamic range) of 87dB
for an output signal frequency of 1MHz.
Operating from
±
5V supplies, the
LTC1666/LTC1667/
LTC1668
can be configured to provide full-scale output
currents up to 10mA. The differential current outputs of
the DACs allow single-ended or true differential operation.
The –1V to 1V output compliance of the
LTC1666/
LTC1667/LTC1668
allows the outputs to be connected
directly to external resistors to produce a differential out-
put voltage without degrading the converter’s linearity. Al-
ternatively, the outputs can be connected to the summing
junction of a high speed operational amplifier, or to a
transformer.
The LTC1666/LTC1667/LTC1668 are pin compatible and
are available in a 28-pin SSOP and are fully specified over
the industrial temperature range.
