1. Describe
The TPA3221DDV is a high power Class D amplifier, Available at full power, idle and support. The device has closed loop feedback Bandwidth up to 100 kHz, it provides low The entire audio band is distorted and provides Excellent sound quality. the device and AD or low idle current HEAD (High Efficiency AD mode) modulation and can drive up to 2 x 105 W into 4-Ω load or 1 x 208 W into 2-Ω load. TPA3221 can be used in single-ended or differential Analog input interface supporting up to 2 VRMS Four selectable gains: 18 dB, 24 dB, 30 dB and 34 Db. The TPA3221 also achieves >90% efficiency, low Idle power (<0.25 W) and ultra-low standby power (<0.1 watts). This can be done by using 70mΩ MOSFET, optimized gate drive scheme and low-power operating modes. The TPA3221 includes a Built-in LDO for easy integration into single-supply systems. To further simplify the design, The unit integrates basic protection functions Including undervoltage, overvoltage, cycle-by-cycle Current Limit, Short Circuit, Clip Detection, overtemperature warning and shutdown, and DC speaker protection.
