Application Information
HA-2544 true differential that versatile offers advantages high unity gain bandwidth, high speed supply current. More important than general purpose applications that HA-2544 especially designed meet requirements found video amplifier system. These requirements include fine picture resolution accurate color rendition, must meet broadcast quality standards. video signal, video information carried amplitude phase well level. amplifier must pass 30Hz line rate Iuminance level 3.58MHz (NTSC) 4.43MHz (PAL) color band without altering phase gain. HA-2544's specifications aimed meeting this include high bandwidth (50MHz), very gain flatness (0.12dB 10MHz), near unmeasurable differential gain differential phase (0.03% 0.03 degrees), noise (20nV/Hz). HA-2544 meets these quidelines.

HA-2544 also offers advantage full output voltage swing ±10V into load. This equates full power bandwidth 2.4MHz this ±10V signal. video signal levels maximum used (with 1k), full power bandwidth would 11.9MHz without clipping distortion. Another usage might required direct load where HA-2544 will still swing this signal shown above display. important note that must realized that load resistance decreases video parameters also degraded. optimal video performance load recommended. lower supply voltages required, such ±5V, many characterization curves indicate where parameters vary. shown bandwidth, slew rate supply current still very well maintained. Prototyping Board Layout When designing with HA-2544 video with high performance device, care should taken high frequency layout techniques avoid unwanted parasitic effects. Short lead lengths, source impedance lower value feedback resistors help reduce unwanted poles zeros. This layout would also include ground plane construction power supply decoupling close supply pins with suggested parallel capacitors 0.1µF 0.001µF ceramic ground. noninverting configuration, amplifier sensitive stray capacitance (<40pF) ground inverting input. Therefore, inverting node connections should kept minimum. Phase shift will also introduced load parasitic capacitance increased. small series resistor 100) before capacitance effectively decouples this effect. Stability/Phase Margin/Compensation HA-2544 sacrificed unity gain stability achieving superb performance. this device, phase margin exceeds degrees unity crossing point open loop frequency response. Large phase margin critical order reduce differential phase differential gain errors caused most other amps. Because this part unity gain stable, compensation brought out. compensation desired reduce noise bandwidth, most standard methods used. method suggested inverting scheme would series from inverting node ground which will reduce bandwidth, effect slew rate. user wishes achieve even higher bandwidth (>50MHz), tolerate some slight gain peaking lower phase margin, experimenting with various load capacitance done.
