Gain Setting (Functions of the Input and Gain Adjustment Pins)
The figures present overviews of the V
IN
and VG pin circuits. (These are the same as the block diagrams.)
1. Consider resistors (11 k
, typical) to be inserted between the V
IN
and VG pins. This should be seen as being the
same as the operational amplifier noninverting input (V
IN+
).
2. If the VG pins are not used, and only the V
IN
pins are used, the BTL gain (across the V
O+
and V
O-
outputs) will be 7
dB for channels 1 and 2 (amplifier units: 1 dB + BTL: 6 dB) and 14 dB for channels 3 and 4 (amplifier units: 8 dB +
BTL: 6 dB).
If the V
IN
pins are not used and 11 k
external resistors are attached to the VG pins, input to the opposite ends of
those resistors will result in equivalent circuit operation. However, the V
IN
pins should be used and the gain set to
minimize the I/O gain temperature characteristics.
Offset Voltage
This IC includes built-in level shifting circuits. For input to which V
REF
is applied as a reference, the output is referenced
to the voltage V
SS
1/2 (V) for channels 1 and 2, and the output is referenced to the voltage (V
SS
2 – V
BE
(0.7))/2 (V) for
channels 3 and 4.
