GENERAL DESCRIPTION
The SPT5510 is a 16-bit, 200 MWPS digital-to-analog
converter designed for high-resolution waveform synthesis
for test and measurement instrumentation applications. It
features true 16-bit linearity, with differential non-linearity of
typically
鹵0.6
LSB and integral non-linearity of
鹵0.75
LSB. It
has a very high-speed update rate of up to 200 MHz and is
ECL compatible. It has an ultrafast settling time of 25 ns to
0.01% and 35 ns to 0.0008%.
The SPT5510 operates over an industrial temperature
range of 鈥?0
擄C
to +85
擄C
and is available in a 10 x 10 mm,
44-lead metric quad flat pack (MQFP) plastic package.
