TPA3001D1PWPR

The TPA3001D1PWPR is a 20W monaural bridge-tied load (BTL) Class D Audio Power Amplifier with high efficiency, eliminating the need for heat sinks. The TPA3001D1 can drive 4 or 8Ω 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 36dB. 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.

• Short-circuit protection (short to VCC, short to GND, short between outputs)
• Replaces large LC filter with small, ferrite bead filter in most applications
• Improved efficiency
• Improved SNR
• 8mA typical at 12V Low supply current
• <lt/>1µA shutdown current
• Green product and no Sb/Br
