ACA0861 - A, B, C, D
Input Stages
The ACA0861A and the ACA0861C are designed
as input stages and are specified at +34 dBmV flat
output. These parts can be used alone for low gain,
low output level applications or can be cascaded with
one of the ACA0861 output stages for higher gain
and output signal drive level. The ACA0861A is a low
power dissipation part designed to drive the ACA0861B
output stage. The ACA0861C is a slightly higher power
dissipation part and provides the needed distortion
parameters to drive the ACA0861D output stage.
Output Stages
The ACA0861B and ACA0861D are designed as
output stages and are specified at +44 dBmV flat
output. These parts can be used alone for low gain,
high output level applications or can be cascaded with
one of the ACA0861 input stages for higher gain. The
ACA0861B is a low power dissipation part designed
as the output stage with an ACA0861A input stage.
The ACA0861D is a higher power dissipation part
designed as the output stage with an ACA0861C
input stage. Cascaded, an ACA0861A and ACA0861B
provide exceptional push-pull hybrid equivalent
performance; an ACA0861C and an ACA0861D
cascaded provide exceptional power doubling hybrid
equivalent performance.
