HV256
32-Channel High Voltage Amplifier Array
11/20/02
Product Overview:
The HV256 is a 32-channel high voltage amplifier
array integrated circuit featuring programmable,
external current limit on each amplifier. Each
channel is configured as a noninverting amplifier.
The maximum output voltage swing is 5V below
the V
high voltage supply. The outputs can
drive capacitive loads of up to 3000pF. Typical
slew rate under a no load condition is 2.0V/μs.
The amplifier has an internal closed loop gain of
37dB or 72V/V saving the user from having to
use external gain setting resistors. When a DAC
voltage of 4.096 is applied to the input of an
amplifier an output voltage of 295V will be cre-
ated.
The HV256 operates on a 300V supply and two
low voltage supplies, 8.0V and -7.0V. It is de-
signed to operate on minimal power featuring a
low quiescent current, while still maintaining a
slew rate of 2.0V/μs. To further reduce power
consumption, high value gain setting resistors
are used for the internal feedback path. The
output current for all 32 channels can be ad-
justed via two external resistors. This allows the
user to set the amount of output current during a
shorted condition. An integrated diode is also
included to help monitor die temperature.
