... 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 allow the designer to specify a high (V clamp voltage. The output signal will clamp at these specified levels. Utilizing a unique patent pending CLAMPIN™ ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8036/AD8037 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... This can be observed by noting the bandwidth specification, between the AD8036 (gain of 1) and AD8037 (gain of 2). The AD8036/ AD8037 typically maintain 65 degrees of phase margin. This high margin minimizes the effects of signal and noise peaking. ...

... L INPUT CLAMPING AMPLIFIER OPERATION The key to the AD8036 and AD8037’s fast, accurate clamp and amplifier performance is their unique patent pending CLAMPIN input clamp architecture. This new design reduces clamp errors by more than 10× over previous output clamp based circuits, as well as substantially increasing the bandwidth, precision and versatility of the clamp inputs ...

... For instance, to set an output limit of ± for an AD8037 operating at a gain of 3. would need to be set to +0.333 V and –0.333 V, respectively. L The only restriction on using the AD8036’s and AD8037’ pins as inputs is that the maximum voltage differ- ...

... For this circuit a gain of two was chosen which allows the use of the AD8037. The feedback resistor, R2, is set at 301 Ω for optimum performance of the AD8037 at a gain of two. There is an interaction between the offset and the gain, so some calculations must be performed to arrive at the proper values for R1 and R3 ...

... IN 1.3k –15V 274 The circuit uses an AD8037 operating at a gain of two with an AD811 to boost the output to the ± range. The AD811 was chosen for its ability to operate with ± supplies and its high slew rate. R1 and R2 act as a level shifter to make the TTL signal levels be approximately symmetrical above and below ground ...

... MODULATION IN The positive input of the AD8037 is driven with a square wave of sufficient amplitude to produce clamping action at both the high and low levels. This is the higher frequency carrier signal. The modulation signal is applied to both the input of a unity gain inverting amplifier and biased at 0 ...
