DESCRIPTION
The LMH6732 is an adjustable supply current, current-feedback operational amplifier. Supply current and
consequently dynamic performance can be easily adjusted by selecting the value of a single external resistor
(R
P
).
NOTE
The following discussion uses the SOIC package pin numbers. For the corresponding
SOT-23 package pin numbers, please refer to the Connection Diagrams section.
SELECTING AN OPERATING POINT
The operating point is determined by the supply current which in turn is determined by current (I
P
) flowing out of
pin 8. As the supply current is increased, the following effects will be observed:
