DESCRIPTION
DC reference buffer input
Positive signal input to D2S
Negative signal input to D2S
Internal SPDT switch control: low selects the internal path, and high selects the external path
Negative supply for input stage
D2S external output
Ground for control pins reference
Negative supply for output stage
External OPS noninverting input
Output power stage shutdown control: low enables the OPS, and high disables the OPS
OPS output
OPS inverting input
Positive supply for output stage
DC offsetting input to D2S
DC reference buffer output
Positive supply for input stage
Connect the thermal pad to GND for single-supply and split-supply operation. See Thermal
Considerations section for more information.
(1) Throughout this document +V_CC refers to the voltage applied at the +VCC1 and +VCC2 pins, and –V_CC is the voltage applied at the
–VCC1 and –VCC2 pins
