HA-2444
50MHz, Selectable, Four Channel
Video Operational Amplifier
The HA-2444 is a channel-selectable video op amp
consisting of four differential inputs, a single-ended output,
and digital control circuitry allowing two digital inputs to
activate one of the four differential inputs. The HA-2444 also
includes a high impedance output state allowing the outputs
of multiple HA-2444s to be wire-OR’d. Functionally, the
HA-2444 is equivalent to four wideband video op amps and
a wideband multiplexer.
Unlike similar competitor devices, the HA-2444 is not
restricted to multiplexing. Any op amp configuration can be
used with any of the inputs. Signal amplification, addition,
integration, and more can be put under digital control with
broadcast quality performance.
The key video parameters of the HA-2444 have been
optimized without compromising DC performance. Gain
Flatness to 10MHz is only 0.1dB. Differential gain and phase
are typically 0.03% and 0.03 degrees, respectively. Laser
trimming allows offset voltages in the 4.0mV range and a
unique common current source design assures minimal
channel-to-channel mismatch, while maintaining 60dB of
crosstalk rejection at 5MHz. Open loop gain of 76dB and low
input offset and bias currents enhance the performance of
this versatile device.
For information about military grade devices, please refer to
the HA-2444/883 data sheet.
