The AD8037-EP exhibits Qualification data available on request an exceptionally fast and accurate pulse response (16 ns to 0.01%), APPLICATIONS extremely wide small-signal and large-signal bandwidths and ADC buffer ultralow distortion. The AD8037-EP recovers from 2 clamp IF/RF signal processing overdrive within 1.5 ns. These characteristics position the High quality imaging AD8037-EP ideally for driving as well as buffering flash and Broadcast video systems high resolution ADCs. Video amplifier In addition to traditional output clamp amplifier applications, Full wave rectifier the input clamp architecture supports the clamp levels as additional input to the amplifier. As such, in addition to static GENERAL DESCRIPTION dc clamp levels, signals with speeds up to 240 MHz can be The AD8037-EP is a wide bandwidth, low distortion clamping applied to the clamp pins. The clamp values can be set to any amplifier. The AD8037-EP is stable at a gain of two or greater. This value within the output voltage range provided that VH is greater device allows the designer to specify a high (V ) and low (V ) CH CL than VL. Due to these clamp characteristics, the AD8037-EP output clamp voltage. The output signal clamps at these specified can be used in nontraditional applications such as a full wave levels. Utilizing a unique patent pending CLAMPING input rectifier, a pulse generator, or an amplitude modulator. These clamp architecture, the AD8037-EP offers a 10 improvement in novel applications are only examples of some of the diverse clamp performance compared to traditional output clamping applications which can be designed with input clamps. devices. In particular, clamp error is typically 3 mV or less and distortion in the clamp region is minimized. This product can be Additional application and technical information can be found used as a classical op amp or clamp amplifier. in the AD8037 data sheet.
