The recommended operating voltage range for the TDA7021TD-T is 2.7V to 5.5V, although it can operate down to 2.3V with reduced performance.
To ensure proper power-up and initialization, apply a stable voltage supply, wait for the internal voltage regulator to settle (typically 10ms), and then apply a logic high to the EN pin. Wait for the internal reset to complete (typically 100ms) before applying input signals.
The maximum input signal amplitude that the TDA7021TD-T can handle is 1.5Vpp differential, although it's recommended to keep the input signal amplitude below 1Vpp to ensure optimal performance and minimize distortion.
To optimize performance, ensure proper PCB layout, use a stable voltage supply, and optimize the input impedance matching. Additionally, adjust the gain settings and filter configurations according to your specific application requirements.
The typical current consumption of the TDA7021TD-T is around 12mA, although this can vary depending on the operating frequency, gain settings, and input signal amplitude.
