DESCRIPTIO
The LT
廬
3469 is a transconductance (g
m
) amplifier that can
drive outputs up to 33V from a 5V or 12V supply. An
internal switching regulator generates a boosted supply
voltage for the g
m
amplifier. The amplifier can drive
capacitive loads in the range of 5nF to 300nF. Slew rate is
limited only by the maximum output current. The 35V
output voltage capability of the switching regulator, along
with the high supply voltage of the amplifier, combine to
allow the wide output voltage range needed to drive a
piezoceramic microactuator.
The LT3469 switching regulator switches at 1.3MHz,
allowing the use of tiny external components. The output
capacitor can be as small as 0.22碌F, saving space and cost
versus alternative solutions.
The LT3469 is available in a low profile ThinSOT
TM
package.
