The AD8037-EP is stable at a gain of two or greater. This device allows the designer to specify a high (VCH) and low (VCL) output clamp voltage. The output signal clamps at these specified levels. Utilizing a unique patent pending CLAMPING™ input clamp architecture, the AD8037-EP offers a 10× improvement in clamp performance compared to traditional output clamping devices. In particular, clamp error is typically 3 mV or less and distortion in the clamp region is minimized. This product can be used as a classical op amp or clamp amplifier. Rev. 0 The AD8037-EP, which utilizes a voltage feedback architecture, meets the requirement of many applications which previously depended on current feedback amplifiers. The AD8037-EP exhibits an exceptionally fast and accurate pulse response (16 ns to 0.01%), extremely wide small-signal and large-signal bandwidths and ultralow distortion. The AD8037-EP recovers from 2× clamp overdrive within 1.5 ns. These characteristics position the AD8037-EP ideally for driving as well as buffering flash and high resolution ADCs. In addition to traditional output clamp amplifier applications, the input clamp architecture supports the clamp levels as additional input to the amplifier. As such, in addition to static dc clamp levels, signals with speeds up to 240 MHz can be applied to the clamp pins. The clamp values can be set to any value within the output voltage range provided that VH is greater than VL. Due to these clamp characteristics, the AD8037-EP can be used in nontraditional applications such as a full wave rectifier, a pulse generator, or an amplitude modulator. These novel applications are only examples of some of the diverse applications which can be designed with input clamps. Additional application and technical information can be found in the AD8037 data sheet. Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.

The maximum power that can be safely dissipated by these devices is limited by the associated rise in junction temperature. The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately 150oC. Exceeding this limit temporarily may cause a shift in parametric performance due to a change in the stresses exerted on the die by the package. Exceeding a junction temperature of 175oC for an extended period can result in device failure. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Although the AD8037-EP is internally short-circuit protected, this may not be sufficient to guarantee that the maximum junction temperature (150°C) is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves. THERMAL RESISTANCE Thermal performance is directly linked to printed circuit board (PCB) design and operating environment. Careful attention to PCB thermal design is required. Table 3.
