General Description

The LPA2010S is a 3-W high efficiency filter-free mono class-D audio power amplifier (class-D amp) that requires only few external components. Its low THD+N feature offers high-quality sound reproduction. The new filter less architecture allows the device to drive speakers directly instead of using low-pass output filters thus saving PCB area and system cost.
The LPA2010S contains circuitry to prevent “pop and click” noise that would occur during turn-on and turn-off transitions. For maximum flexibility, the LPA2010S provides an externally controlled gain (with resistors), as well as an externally controlled turn-on and turn-off times (with the bypass capacitor). The LPA2010S is capable of delivering 2.8W of continuous average power to a 4? load from a 5V power supply with less than 10% distortion (THD+N). The device utilizes a fully differential architecture, a full-bridged output, and a low-EMI modulation scheme.
The LPA2010S is designed specifically to provide high quality output audio power with a minimal number of external components. The LPA2010S does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited where minimal board or solution size is a primary requirement. It features a low-power shutdown mode, which is achieved by driving the SD pin with logic low. Additionally, the LPA2010S features output short-circuit protection and internal thermal-overload protection.
The LPA2010S is available in a MSOP8&DFN-8 package.
