General Description
The Supertex 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, V
DD
and V
NN
.
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 V
PP
high voltage supply. The outputs can drive capaci-
tive loads of up to 3000pF.
The maximum output source and sink current can be adjusted
by using two external resistors. An external R
SOURCE
resistor
controls the maximum sourcing current and an external R
SINK
resistor controls the maximum sinking current. The current limit
is approximately 12.5V divided by the external resistor value.
The setting is common for all 32 outputs. A low voltage silicon
junction diode is made available to help monitor the die
temperature.

Power Up/Down Sequence
The device can be damaged due to improper power up / down
sequence. To prevent damage, please follow the acceptable
power up /down sequences and add two external diodes as shown
in the diagram below. The first diode is a high voltage diode
across V
PP
and V
DD
where the anode of the diode is connected
to V
DD
and the cathode of the diode is connected to Vpp. Any low
current high voltage diode such as a 1N4004 will be adequate.
The second diode is a schottky diode across V
NN
and DGnd where
the anode of the schottky diode is connected to V
NN
and the
cathode is connected to DGnd. Any low current schottky diode
such as a 1N5817 will be adequate.
