MAX4806, MAX4807, MAX4808 提供有源钳位，大大降低2次谐波输出

简介

The MAX4806/MAX4807/MAX4808 integrated circuits generate high-voltage, high-frequency, unipolar or bipolar pulses from low-voltage logic inputs. These dual pulsers provide independent logic inputs, independent high-voltage pulser outputs with active clamps, and independent high-voltage supply inputs.

The MAX4806/MAX4807/MAX4808 feature a 6 output impedance for the high-voltage outputs, and a 20 impedance for the active clamp. The high-voltage outputs are guaranteed to provide 2A of output current.

All devices use three logic inputs per channel to control the positive and negative pulses and active clamp. Also included are two independent enable inputs. Disabling EN ensures that the output MOSFETs are not accidentally turned on during fast power-supply ramping. This allows for faster ramp times and smaller delays between pulsing modes. A low-power shutdown mode minimizes power consumption to less than 1µA. All digital inputs are CMOS compatible.

The MAX4806 includes clamp output overvoltage protection, while the MAX4807 features both pulser output and clamp output overvoltage protection. The MAX4808 does not provide overvoltage protection. (See the Ordering Information/Selector Guide).

The MAX4806/MAX4807/MAX4808 are available in a 7mm x 7mm, 56-pin, TQFN exposed-pad package are specified over the 0°C to +70°C commercial temperature range.
