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 5 (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 1kΩ 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 RL = 1kΩ), the full power bandwidth would be 11.9MHz without clipping distortion. HA-2544 Another usage might be required for a direct 50Ω or 75Ω load where the HA-2544 will still swing this ±2V signal as shown in the above display. One important note that must be realized is that as load resistance decreases the video parameters are also degraded. For optimal video performance a 1kΩ load is recommended. If lower supply voltages are required, such as ±5V, many of the characterization curves indicate where the parameters vary. As shown the bandwidth, slew rate and supply current are still very well maintained. Prototyping and PC Board Layout When designing with the HA-2544 video op amp as with any high performance device, care should be taken to use high frequency layout techniques to avoid unwanted parasitic effects. Short lead lengths, low source impedance and lower value feedback resistors help reduce unwanted poles or zeros. This layout would also include ground plane construction and power supply decoupling as close to the supply pins with suggested parallel capacitors of 0.1µF and 0.001µF ceramic to ground. In the noninverting configuration, the amplifier is sensitive to stray capacitance (<40pF) to ground at the inverting input. Therefore, the inverting node connections should be kept to a minimum. Phase shift will also be introduced as load parasitic capacitance is increased. A small series resistor (20Ω to 100Ω) before the capacitance effectively decouples this effect. Stability/Phase Margin/Compensation The HA-2544 has not sacrificed unity gain stability in achieving its superb AC performance. For this device, the phase margin exceeds 60 degrees at the unity crossing point of the open loop frequency response. Large phase margin is critical in order to reduce the differential phase and differential gain errors caused by most other op amps. Because this part is unity gain stable, no compensation pin is brought out. If compensation is desired to reduce the noise bandwidth, most standard methods may be used. One method suggested for an inverting scheme would be a series R-C from the inverting node to ground which will reduce bandwidth, but not effect slew rate. If the user wishes to achieve even higher bandwidth (>50MHz), and can tolerate some slight gain peaking and lower phase margin, experimenting with various load capacitance can be done. Shown in Application 1 is an excellent Differential Input, Unity Gain Buffer which also will terminate a cable to 75Ω and reject common mode voltages. Application 2 is a method of separating a video signal up into the Sync only signal and the Video and Blanking signal. Application 3 shows the HA-2544 being used as a 100kHz High Pass 2-Pole Butterworth Filter. Also shown is the measured frequency response curves.
