Sell Wide Bandwidth Voltage Feedback Clamp Amps.

Description

The AD***6 and AD***7 are wide bandwidth, low distortion

clamping amplifiers. The AD***6 is unity gain stable. The

AD***7 is stable at a gain of two or greater. These devices al-

low 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 AD***6 and AD***7 offer a *0× 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 AD***6 and AD***7, which utilize a voltage feedback ar-

chitecture, meet the requirements of many applications which

previously depended on current feedback amplifiers. The

AD***6 and AD***7 exhibit an exceptionally fast and accurate

pulse response (*6 ns to 0.*1%), extremely wide small-signal

and large-signal bandwidths and ultralow distortion. The

AD***6 achieves –*6 dBc at *0 MHz, and **0 MHz small-

signal and **5 MHz large-signal bandwidths. The AD***6 and

AD***7’srecover from 2× clamp overdrive within 1.5 ns.

These characteristics position the AD***6/AD***7 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 **0 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 AD***6 and

AD***7 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.

The AD***6 is offered in chips, industrial(–*0°Cto +*5°C)

and military (–*5°Cto +**5°C) package temperature ranges

and the AD***7 inindustrial. Industrial versions are available

in plastic DIP and SOIC; MIL versions are packaged in cerdip.
