100MHz Op Amp Features Low Noise Rail-to-Rail Performance
While Consuming Only 2.5mA вЂ“ Design Note 308
Glen Brisebois
The new LTВ®6202 op amp combines 100MHz gainbandwidth, 1.9nV/в€љHz voltage noise and rail-to-rail
inputs and outputs, while consuming only 2.5mA. It
also features a low 0.75pA/в€љHz current noise, and it
contributes exceptionally low total noise and distortion
power in small-signal applications. The device is fully
speciп¬Ѓed on 3V, 5V and В±5V supplies and is available in
commercial and industrial temperature grades in both
the SOT and SO packages. Dual and quad versions are
also available as the LT6203 and LT6204, respectively.
Low Power, 2.4nV/в€љHz, Photodiode AC
Transimpedance Ampliп¬Ѓer Outperforms
Monolithic Solutions
You canвЂ™t optimize for everything. Op amp designs
that try to squeeze good JFETs into their high speed
monolithic processes inevitably compromise other
parameters, usually resulting in high supply currents.
Figure 1 shows a simple way to get the best of both
worlds using the LT6202 and a low noise discrete
JFET. The JFET acts as a source follower, buffering the
inverting input of the LT6202 and making it suitable for …

Driving a Low Noise, Low Distortion 18-Bit, 1.6Msps ADC
Design Note 494
Guy Hoover
Introduction
The LTC В®2379-18 is an 18-bit, 1.6Msps SAR ADC with
an extremely high SNR of 101dB and THD of вЂ“120dB. It
also features a unique digital-gain compression function,
which eliminates the need for a negative supply in the
ADC driver circuit. the LTВ®6203 and minimizes disturbances reflected into
the LT6203 from sampling transients. The 32k point FFT
in Figure 2 shows the performance of the LTC2379-18 in
the circuit of Figure 1.
Single Supply Driver
The circuit of Figure 3 uses the digital gain compression
feature of the LTC2379-18, which defines the ADC full-scale
input swing to be 10% to 90% of the reference voltage.
This means that for a 5V reference the full-scale swing is Designing a driver circuit to get the best possible performance from the LTC2379-18 is not difficult. The two
circuits presented here demonstrate differential and
single-ended solutions using dual and single supplies.
Note that the components used here have been carefully
chosen with the ADCвЂ™s accuracy and acquisition time
requirements in mind, so any modifications should be
thoroughly tested. L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of …

High Speed Low Noise Op Amp Family Challenges Power and Distortion Assumptions with Rail-to-Rail Inputs and Output &mdash LT Journal

DESIGN FEATURES High Speed Low Noise Op Amp
Family Challenges Power and
Distortion Assumptions with Rail-to-Rail
Inputs and Output by John Wright and Glen Brisbois
Do the Math The tradeoff is all too familiar; low
noise op amps dissipate high power.
The 1.9nV/в€љHz LT6202, however,
doesnвЂ™t follow this rule. It provides
rail-to-rail input and output operation
(meaning that maximum dynamic
range can now be extracted on low
supply voltages) with a supply current of only 2.5mA. The LT6200 offers
even lower noise (0.95nV/в€љHz) and
distortion, and it includes a shutdown feature for standby conditions.
These unity gain stable amplifiers are
well suited to fast low noise applications because of their respective
100MHz and 165MHz gain bandwidth,
low distortion, guaranteed noise specifications, and low offset voltage. The
amplifiers operate on a total supply
voltage of 2.5V to 12.6V, and are
fabricated on Linear TechnologyвЂ™s high
speed complimentary bipolar process.
All are specified with 3V, 5V, and В±5V …
