Low Power High Voltage Amplifier
Certain materials used in optical applications have charac-
teristics that change due to the presence and strength of
a DC electric field. The voltage applied across these
materials should be precisely controlled to maintain de-
sired properties, sometimes as high as 100’s of volts. The
materials are not conductive and represent a capacitive
load.
The circuit of Figure 6 shows the LT1800 used in an
amplifier capable of a 250V output swing and providing

TYPICAL APPLICATIO
precise DC output voltage. When no signal is present, the
op amp output sits at about mid-supply. Transistors Q1
and Q3 create bias voltages for Q2 and Q4, which are
forced into a low quiescent current by degeneration resis-
tors R4 and R5. When a transient signal arrives at V
IN
, the
op amp output moves and causes the current in Q2 or Q4
to change depending on the signal polarity. The current,
limited by the clipping of the LT1800 output and the 3k
of total emitter degeneration, is mirrored to the output
devices to drive the capacitive load. The LT1800 output
then returns to near mid-supply, providing the precise DC
output voltage to the load. The attention to limit the current
of the output devices minimizes power dissipation thus
allowing for dense layout, and inherits better reliability.
Figure 7 shows the time domain response of the amplifier
providing a 200V output swing into a 100pF load.
