The built-in converter generates a 5.75-V supply voltage for the Class-D amplifier when high output power is required. The device has a integrated low-pass filter to improve the RF rejection and reduce DAC out-of-band noise, increasing the signal-to-noise ratio (SNR). 9.2 Functional Block Diagram 9.3 Feature Description 9.3.1 Fully Differential Amplifier The TPA2080D1 is a fully differential amplifier with differential inputs and outputs. The fully differential amplifier consists of a differential amplifier with common-mode feedback. The differential amplifier ensures that the amplifier outputs a differential voltage on the output that is equal to the differential input times the gain. The common-mode feedback ensures that the common-mode voltage at the output is biased around VCC/2 regardless of the common-mode voltage at the input. The fully differential TPA2080D1 can still be used with a single-ended input; however, the TPA2080D1 must be used with differential inputs when in a noisy environment, like a wireless handset, to ensure maximum noise rejection. 9.3.1.1 Advantages of Fully Differential Amplifiers • Input-coupling capacitors not required: – The fully differential amplifier allows the inputs to be biased at voltage other than mid-supply.
