HA-2406
30MHz, Digitally Selectable Four Channel
Operational Amplifier
The HA-2406 is a monolithic device consisting of four op
amp input stages that can be individually connected to one
output stage by decoding two TTL lines into four channel
select signals. In addition to allowing each channel to be
addressed, an enable control disconnects all input stages
from the output stage when asserted low.
Each input-output combination of the HA-2406 is designed
to be a 20V/
s, 30MHz gain-bandwidth amplifier that is
stable at a gain of ten. By connecting one external 15pF
capacitor all amplifiers are compensated for unity gain
operation. The compensation lead may also be used to limit
the output swing to TTL levels through suitable clamping
diodes and divider networks (see Application Note AN514).
Dielectric isolation and short-circuit protected output stages
contribute to the quality and durability of the HA-2406. When
used as a simple amplifier, its dynamic performance is very
good and when its added versatility is considered, the
HA-2406 is unmatched in the analog world. It can replace a
number of individual components in analog signal
conditioning circuits for digital signal processing systems. Its
advantages include saving board space and reducing power
supply requirements.

impedance during Disable, see HA2444.
