Quad, High Voltage
Amplifier Array Demo Board
General Description
The Supertex HV264TS-G is a quad high voltage amplifier
array device in a 24-pin TSSOP package. The HV264DB1
demo board provides a platform to evaluate this device.
This demoboard requires only a minimum setup including
a VDD low voltage supply, a VPP high voltage supply, and
a signal source. The demoboard provides the input/output
connections through two 6-pin headers.

Power Up/Down Sequence
The device can be damaged due to an improper power up /
down sequence. To prevent damage, please follow the ac-
ceptable power up / down sequences. An external diode
across VPP and VDD in included on the board, where the
anode of the diode is connected to VDD and the cathode is
connected to VPP. Any low current high voltage diode will be
adequate.
Acceptable Power Up Sequences
1) VDD 2) VPP 3) Inputs
1) VDD 2) Inputs 3) VPP
Acceptable Power Down Sequences
1) Inputs, 2) VPP) VDD
1) VPP) Inputs) VDD
Gain Setting
The HV264 quad amplifier array has the internal built-in gain
setting resistors available with a fixed gain of 66.7V/V +/- 5%.
External gain setting resistors can be used for applications
that require better tolerance or a different closed loop gain. An
example is shown in the following schematics. Fig. 1 shows
the schematics of the demoboard. The external resistor val-
ues and tolerances can be selected to meet different gain set-
ting and precision requirements as shown in Fig. 2.
