General Description
The Supertex HV257 is a 32-channel high voltage sample and
hold 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
.
All 32 sample and hold circuits share a common analog input,
Vsig. The individual sample and hold circuits are selected by a
5 to 32 logic decoder. The sampled voltage on the holding
capacitor is buffered by a low voltage amplifier and amplified by
a high voltage amplifier with a closed loop gain of 72V/V. The
internal closed loop gain is set for an input voltage range of 0V
to 4.096V. The input voltage can be up to 5.0V, but the output will
saturate. The maximum output voltage swing is 5V below the V
PP
high voltage supply. The outputs can drive capacitive 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.
