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

±0.6 LSB and integral non-linearity of ±0.75 LSB. It

FEATURES

• 16-Bit, 200 MWPS digital-to-analog converter

• Differential linearity of

±0.6 LSB (typical)

• Integral linearity of

±0.75 LSB (typical)

• Fast settling time: 35 ns to 0.0008%; 25 ns to 0.01%

• Low glitch energy

• On-chip voltage reference

• ECL compatibility

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 –40

°C to +85 °C and is available in a 10 x 10 mm,

44-lead metric quad flat pack (MQFP) plastic package.
