The TPA3001D1 (sometimes referred to as TPA3001) is a 20-W monaural bridge-tied load (BTL) class-D audio power amplifier (class-D amp) with high efficiency, eliminating the need for heat sinks. The TPA3001D1 can drive 4- or 8- speakers with only a ferrite bead filter required to reduce EMI.
●The gain of the amplifier is controlled by two input terminals, GAIN1 and GAIN0. This allows the amplifier to be configured for a gain of 12, 18, 23.6, or 36 dB. The differential input stage provides high common-mode rejection and improved power-supply rejection.
●The amplifier also includes depop circuitry to reduce the amount of pop at power-up and when cycling SHUTDOWN.
●The TPA3001D1 (TPA3001) is available in the 24-pin thermally enhanced TSSOP package (PWP), which eliminates the need for an external heat sink.
● 20 W Into 8- Load From 18-V Supply (10% THD+N)
● Short-Circuit Protection (Short to VCC, Short to GND,
●Short Between Outputs)
● Third-Generation Modulation Technique:
● Replaces Large LC Filter With Small, Low-Cost Ferrite
●Bead Filter in Most Applications
● Improved Efficiency
