Rise and fall times of 4ns and drive capability of 22Vpp and 100mA add to the KH300’s impressive specifications. Using the KH300 is as easy as adding power supplies and a gain-setting resistor. Unlike conventional op amp designs in which optimum gain-bandwidth product occurs at a high gain, minimum settling time at a gain of -1, maximum slew rate at a gain of +1, et cetera, the KH300 offers consistent performance at gain settings from 1 to 40 inverting or non-inverting. As a result, designing with the KH300 is greatly simplified. And since no external compensation is necessary, “tweeks” on the production line have been eliminated, making the KH300 an efficient component for use in production situations. Flat gain and phase response from DC to 45MHz and superior rise and fall times make the KH300 an ideal amplifier for a broad range of pulse, analog, and digital applications. A 45MHz full power bandwidth (20Vpp into 100Ω) and 3000V/µsec slew rate eliminate the need for power buffers in many applications such as driving “flash” A to D converters or linedriving. For applications requiring lower power consumption, the KH300 can operate on supplies as low as ±5V. Fast overload recovery (20ns) helps prevent lo...
