Schematic Diagram
Application Information
The HA-2544 is a true differential op amp that is as versatile
as any op amp but offers the advantages of high unity gain
bandwidth, high speed and low supply current. More
important than its general purpose applications is that the
HA-2544 was especially designed to meet the requirements
found in a video amplifier system. These requirements
include fine picture resolution and accurate color rendition,
and must meet broadcast quality standards.
In a video signal, the video information is carried in the
amplitude and phase as well as in the DC level. The amplifier
must pass the 30Hz line rate Iuminance level and the 3.58MHz
(NTSC) or 4.43MHz (PAL) color band without altering phase or
gain. The HA-2544’s key specifications aimed at meeting this
include high bandwidth (50MHz), very low gain flatness
(0.12dB at 10MHz), near unmeasurable differential gain and
differential phase (0.03% and 0.03 degrees), and low noise
(20nV/
√
Hz). The HA-2544 meets these guidelines.
The HA-2544 also offers the advantage of a full output voltage
swing of
±
10V into a 1k
load. This equates to a full power
bandwidth of 2.4MHz for this
±
10V signal. If video signal
levels of
±
2V maximum is used (with R
L
= 1k
), the full power
bandwidth would be 11.9MHz without clipping distortion.
