Technical Information (continued)
2.Application Note (continued)
2) Tone characteristics
When the tone control voltage (V
T
, at Pin3) is changed from 2.5 V to 5 V, the high frequency gain is increased
gradually up by a max. of 9 dB. When V
T
is changed from 2.5 V to 0 V, the high frequency gain is decreased
gradually down by a max. of
11 dB.
By increasing the value of the capacitor at Pin2, the treble cut can be further decreased.
3) Volume characteristic
The volume characteristic is logarithmic type. When the volume control voltage (V
V
, at Pin4) is 5 V, the gain is at
max. (30 dB) ; that is, there is no attenuation. When V
V
is decreased, the gain is decreased at the same time. When
V
V
is 0 V, the gain is at its minimum ; that is, there is max. attenuation,
69 dB.
4) Dynamic range
The AN5278 has been designed, specially to have as large an input dynamic range as possible. The input D-range
is about 4.5 V[rms], or 12.7 V[p-p] (conditions of measurement : V
CC
=
18 V, adjust the gain downwards by
decreasing the volume control voltage).
