MAX4810, MAX4811, MAX4812概述

The MAX4810/MAX4811/MAX4812 integrated circuits generate high-voltage, high-frequency, unipolar or bipolar pulses from low-voltage logic inputs. These dual pulsers feature independent logic inputs, independent high-voltage pulser outputs with active clamps and independent high-voltage supply inputs.

The MAX4810/MAX4811/MAX4812 feature a 9Ω output impedance for the high-voltage outputs, and a 27Ω impedance for the active clamp. The high-voltage outputs are guaranteed to provide 1.3A 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 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 reduces power consumption to less than 1µA. All digital inputs are CMOS compatible.

The MAX4810 includes clamp output overvoltage protection, while the MAX4811 features both pulser output and clamp output overvoltage protection. The MAX4812 does not provide overvoltage protection. See the Ordering Information/Selector Guide in the full data sheet.

The MAX4810/MAX4811/MAX4812 are available in a 56-pin (7mm x 7mm), TQFN exposed-pad package and are specified over the 0°C to +70°C commercial temperature range.
