I have recently been using the TPA0211 class AB amplifier to try and power a small speaker. But, After setting it up as in the circuit diagram in the data sheet and as described by the circuit diagram in the user guide of the evaluation kit I can't get it to work in BTL mode. What hapens is both outputs (V+ and V-) seem to keep the same values rather than the differential outputs that they should produce.
Vdd-3.3V
GND-0V
Vin-between 0.5V and 3V
Gain- set to a range of values through potentiometers at input.
