High Performance Op Amps Deliver Precision Waveform
Synthesis вЂ“ Design Note 306

Introduction
With the trend toward ever more precise waveform
generation using DSP synthesis and digital-to-analog
conversion, such as with the LTCВ®1668 16-bit, 50Msps
DAC, increasing demands are being placed on the output
ampliп¬Ѓer. In some applications, the DAC current-tovoltage function is simply resistive, though this is limited
to small-signal situations. The more common solution
is to use an ampliп¬Ѓcation or a transimpedance stage
to provide larger usable scale factors or level shifting.
Figure 1 shows one such example, with an LTВ®1722
performing a differential-current to single-ended voltage ampliп¬Ѓcation for an LTC1668.
The LT1722, LT1723 and LT1724 Low Noise
Ampliп¬Ѓers
The LT1722, LT1723 and LT1724 are single, dual and
quadruple operational ampliп¬Ѓers that feature low noise
and high speed along with miserly power consumption.
The parts are optimized for low voltage operation and
draw only 3.7mA (typical) per section from В±5V supplies,
yet deliver up to 200MHz GBW and quiet 3.8nV/в€љHz, 1.2pA/в€љHz (typical) noise performance. DC characteristics include sub-millivolt input offset precision and
output drive greater than 20mA, excellent for cable …
