HV256
32-Channel High-Voltage Amplifier Array
Features General Description The HV256 is a 32-channel, high-voltage amplifier
array integrated circuit. It operates on a single
high-voltage supply, up to 300V, and two low-voltage
supplies, VDD and VNN. Thirty-two Independent High-voltage Amplifiers
300V Operating Voltage
295V Output Voltage
2.2V/Вµs Typical Output Slew Rate
Adjustable Output Current Source Limit
Adjustable Output Current Sink Limit
Internal Closed-loop Gain of 72V/V
12 MΩ Feedback Impedance
Layout Ideal for Die Applications The input voltage range is from 0V to 4.096V. The
internal closed-loop gain is 72V/V, giving an output
voltage of 295V when 4.096V is applied. Input voltages
of up to 5V can be applied but will cause the output to
saturate. The maximum output voltage swing is 5V
below the VPP high-voltage supply. The outputs can
drive capacitive loads of up to 3000 pF. Applications Microelectromechanical Systems (MEMS) Driver Piezoelectric Transducer Driver Optical Crosspoint Switches
(Using MEMS Technology) The maximum output source and sink currents can be
adjusted by using two external resistors. An external
RSOURCE resistor controls the maximum sourcing …
