General Description
The Supertex HV254 is a 32-channel high voltage amplifier
array integrated circuit. It operates on a 275V high voltage
supply and two low voltage supplies: +5.0V and 鈥?.0V. Each
channel has its own input and output. An integrated diode is
included to help monitor die temperature.
The input voltage can be from a DAC with a voltage range of 0V
to the low voltage supply, V+. The output of the HV254FG will
swing from 7V to 250V. It cannot swing to ground. With the
internal gain set at 50V/V, a minimum input signal of 140mV will
still maintain linearity. Input voltages below 140mV can be
applied without damage to the device. The amplifier, however,
will be saturated.Typical output load is equivalent to a 125Mohm
resistor in parallel with a 100pF capacitor. The outputs have a
guaranteed slew rate of at least 3V/碌s. The internal closed loop
gain is set at a nominal value of 34.0dB (50V/V).
The HV254 is designed to operate with minimal power con-
sumption while maintaining a guaranteed slew rate of 3V/碌s.
High value resistors are used for the gain setting to minimize
current on the feedback path.
