Part Number: TPA3007D1

Function: 6.5W MONO CLASS-D AUDIO POWER AMPLIFIER

Package: 24-pin TSSOP type

Manufacturer: Texas Instruments

Pinouts:

TPA3007D1 datasheet

 

Description

The TPA3007D1 is a 6.5-W mono bridge-tied load (BTL) class-D audio power amplifier with high efficiency, eliminating the need for heat sinks. The TPA3007D1 can drive 8-Ω 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, and 36 dB. The differential input stage provides high common mode rejection and improved power supply rejection.

The amplifier also includes “de-pop” circuitry to reduce the amount of pop at power-up and when cycling SHUTDOWN. The TPA3007D1 is available in the 24-pin TSSOP package (PW) and does not require an external heat sink.

Features

1. 6.5 W Into 8-Ω Load From 12-V Supply(10% THD+N)

2. Short Circuit Protection (Short to VCC, ShGND, Short Between Outputs)

3. Third-Generation Modulation Technique:
(1) Replaces Large LC Filter With Small,Low-Cost Ferrite Bead Filter in Most Applications
(2) Improved Efficiency
(3) Improved SNR

4. Low Supply Current … mA Typ at 12 V

5. Shutdown Control … < 1µA Typ
