Video Signal Distribution Using Low Supply Voltage Amplifiers
Design Note 327
Jon Munson
Introduction
Video designs are often pressed to operate on the lowest
possible rail voltagesвЂ”a simple result of the trend towards lower voltage logic and the advantages of sharing
supply potentials wherever possible. Video designs are
further complicated by the need to accommodate the
dynamic offset variation inherent in AC-coupled designs
as picture content varies. Traditional op amps require
relatively large amounts of output-swing headroom and
are therefore impractical for AC coupling at even 5V.
Linear Technology offers a new family of video op amps
which addresses these issues and offers the ability to
operate down to 3.3V in most instances. This family
includes the LTВ®6205 (single), LT6206 (dual), LT6207
(quad), LT6550 (triple, п¬Ѓxed gain of 2) and LT6551
(quad, п¬Ѓxed gain of 2).
Video Signal Characteristics
To determine the minimum video ampliп¬Ѓer supply voltage, we must п¬Ѓrst examine the nature of the signal.
Composite video is the most commonly used signal
in broadcast-grade products and combines Luma (or
luminance, the intensity information), Chroma (the colorimetry information) and Sync (vertical and horizontal …

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 …
