PIN FUNCTIONS
+INA, –INA, –INB, +INB (Pins 1, 2, 5, 6): Differential
Inputs of A and B channel respectively.
V– (Pins 3, 4, 13, 14, 21):
Negative Power Supply. All
four pins, as well as the exposed back, must be connected
to same voltage/ground.
ENABLEA, ENABLEB (Pins 9, 18): Logic inputs. If low,
the amplier is enabled. If high, the amplier is disabled
and placed in a low-power shutdown mode, making
the amplier outputs high impedance. These pins are
internally separate. These pins should not be left
oating.
V+ A , V+ B (Pins 15, 20, 7, 12 ): Positive Power Supply
(Normallytiedto3Vor3.3V).SupplypinsofAandBchannels
are internally separate. Bypass each pin with 1000pF and
0.1μF capacitors as close to the pins as possible.
–OUTA, +OUTA, –OUTB, +OUTB (Pins 16, 17, 11, 10):
Differential Outputs of channels A and B respectively.
VOCMA, VOCMB (Pins 19, 8): These pins set the output
common mode voltage for the respective channel. They
are internally separate. A 0.1μF external bypass capacitor
is recommended.
Exposed Pad (Pin 21): V –. The Exposed Pad must be
connected to same voltage/ground as pins 3, 4, 13, 14.
