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 addi-

tional 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 V_His greater

that V_L. 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 modula-

tor. These novel applications are only examples of some of the

diverse applications which can be designed with input clamps.

PRODUCT DESCRIPTION

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 al-

low the designer to specify a high (V_CH) and low (V_CL) 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× im-

provement in clamp performance compared to traditional out-

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 am-

plifier where a high and low output voltage are specified.

The AD8036 is offered in chips, industrial (–40°C to +85°C)

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.

The AD8036 and AD8037, which utilize a voltage feedback ar-

chitecture, 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
