The Krohn-Hite Models 7600 and 7602 are 17 watt and 34 watt, wideband power amplifiers that offer extended output power and voltage capabilities, low distortion, versatility and the latest in hybrid CMOS power operational amplifier technology with performance features not available in other power amplifiers.

The Models 7600 provide 17 watts of continuous power (34 watts at dc) and 141V rms from dc to 500kHz. The frequency response of the 7600 is ±0.1dB to 10kHz, and the distortion contributed by the amplifier is <0.01% to 5kHz and <0.3% to 100kHz. The voltage gain can be either inverting or non-inverting and has selectable ranges from 0dB-14dB, 0dB-28dB and 0dB-42dB, and is continuously variable between ranges.

Other features include: modes of A, A–B and –B, common mode rejection of 80dB, input coupling of ac or dc, dc offset control that is variable from 0V to ±200V; an optional meter package that provides a meter for displaying the heat sink temperature in °C, output peak voltage and average output current.

The Model 7602 provides the same performance as the Model 7600 with a differential output and is able to deliver 34 watts of continuous power (68 watts at dc) and 282V rms (800Vp-p). It can also provide plus and minus dc voltages simultaneously.

The Models 7600 and 7602 are two of the only amplifiers on the market today that offer a combination of power, performance and versatility over the range of dc to 1MHz. With the ability to drive either resistive or reactive loads, together with its power and voltage capability, low distortion, and flat response make the Models 7600 and 7602 ideally suited for applications such as driving piezo electric transducers, ion beam deflection, vacuum tube driver, meter calibration, ink jet testing and design; and with the dc coupling and variable dc offset control each amplifier can function as a bipolar high voltage power supply.
