Design Note 1039
Erjon Qirko and Kris Lokere
Introduction
The LT6018 is an ultralow noise (1.2nV/в€љHz at 1kHz)
operational amplifier with ultralow distortion (вЂ“115dB
at 1kHz). It has a gain bandwidth product of 15MHz,
maximum offset voltage of 50ВµV and a maximum
offset voltage drift of 0.5ВµV/В°C. This combination
of features makes it suitable for driving a variety of
high resolution analog-to-digital converters (ADCs).
This Design Note presents circuits and optimization
strategies to achieve the best signal-to-noise ratio
(SNR) and total harmonic distortion (THD) when
using the LT6018 to drive high speed 18-bit and 20bit successive approximation register (SAR) ADCs. LTC2378-20 stands out for its unrivaledВ 2ppm linearity
performance. The best way to create a differential
signal while maintaining linearity is by using the
precision matched resistors in the LT5400 used on
this demo board. A detailed theory of operation for
the circuit shown in Figure 1 appears in Design Note
1032 (where the LT1468 drives the LTC2377-20).
To measure the circuitвЂ™s linearity, an ultrapure sine …
