The AD8036 and AD8037 are wide bandwidth, low distortion clamping amplifiers. The AD8036 is unity gain stable. The AD8037 is stable at a gain of two or greater. These devices allow the designer to specify a high (VCH) and low (VCL) output clamp voltage. The output signal will clamp at these specified levels. Utilizing a unique patent pending CLAMPIN™ input clamp architecture, the AD8036 and AD8037 offer a 10 ×improvement in clamp performance compared to traditional out-V put 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 a clamp amplifier where a high and low output voltage are specified.

The AD8036 and AD8037, which utilize a voltage feedback architecture, meet the requirements of many applications which previously depended on current feedback amplifiers. The AD8036 and AD8037 exhibit an exceptionally fast and accurate pulse response (16 ns to 0.01%), extremely wide small-signal and large-signal bandwidths and ultralow distortion. The AD8036 achieves -66 dBc at 20 MHz, and 240 MHz small-signal and 195 MHz large-signal bandwidths. The AD8036 and AD8037's recover from 2× clamp overdrive within 1.5 ns. These characteristics position the AD8036/AD8037 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 inputs 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 also be set to any value within the output voltage range provided that VH is greater that VL. Due to these clamp characteristics, the AD8036 and AD8037 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.

The AD8036 is offered in chips, industrial (-40°C to +85°) and military (-55°C to +125°C) package temperature ranges and the AD8037 in industrial. Industrial versions are available in plastic DIP and SOIC; MIL versions are packaged in cerdip.

Product Detail

This evaluation board is designed to help users evaluate the AD8037. The evaluation board is a bare board: there are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.

The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials.
