General Description
The MAX4810/MAX4811/MAX4812 integrated circuits
generate high-voltage, high-frequency, unipolar or bipo-
lar 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 9 Ω output
impedance for the high-voltage outputs, and a 27 Ω
impedance for the active clamp. The high-voltage out-
puts 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 puls-
ing 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 pro-
tection, 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.
