PIN FUNCTIONS
+IN2 A, –IN2 A, +IN2 B, –IN2 B (Pins 1, 5, 7, 11): Inputs
to Trimmed 200Ω Resistors. Can accept an input signal,
be fl oated, tied to an output pin, or connected to external
components.
+IN1 A, –IN1 A, +IN1 B, –IN1 B (Pins 2, 4, 8, 10): Inputs
to Trimmed 100Ω Resistors. Can accept an input signal,
be fl oated, tied to an output pin, or connected to external
components.
BIAS A, BIAS B (Pins 3, 9): Three-State Input to Select
Amplifi er Power Consumption. Drive low for shutdown,
drive high for full power, leave fl oating for medium power.
BIAS presents an input resistance of approximately 150k
to a voltage 1.15V above V
V
should be connected to the same voltage, either a ground
plane or a negative supply rail.
