The TDA2075A is a two-channel amplifier driver that uses Tripath's Digital Power Processing (DPPTM) technology. It offers higher integration compared to previous Tripath amplifier driver chipsets while providing exceptional audio performance for real-world applications. The TDA2075A is typically configured as a split-supply, single-ended, stereo amplifier. It can also be configured as a single-supply, single-ended, stereo amplifier through external component choice. For applications that require bridged output drive, please refer to the TDA1400.
The TDA2075A is a two‑channel stereo class‑T digital audio amplifier driver that uses Tripath’s proprietary Digital Power Processing (DPP) technology. It can be configured for split‑supply or single‑supply operation and supports a wide range of output power levels.
This datasheet includes absolute maximum ratings, operating conditions, thermal and electrical characteristics, performance data such as output power and THD, a full pin description, package dimensions, and example application/test circuits to aid designers.
| Supply Voltage (5V) | 5 V |
|---|---|
| Supply Voltage (10V) | 10 V |
| Quiescent Current | 50 mA |
| THD+N (RL=4Ω) | 0.1 % |
| Package | 48‑pin LQFP |
Typical supply voltages are V5 = 5 V, V10 = 10 V, and VPP = |VNN| = 40 V, but the chip can also operate from a single supply with appropriate external components.
The chip is supplied in a 48‑pin LQFP package.
