Upgrade to myMPS+Product Description
The EV1740EC-00A is the evaluation board for the MP1740, a low-power mono BTL class-D audio amplifier. It is one of MPS’s products in a very small WLCSP package, high efficiency, and full bridge output structure capable of delivering 3W into 4Ω speaker.
The gain of this module is set at 2V/V, and can be easily programmed by changing the input resistors.

IC Details
The MP1740 is a high efficiency Class-D H-bridge audio amplifier. It utilizes a full bridge output structure capable of delivering 3W into 4O speaker. The device exhibits the high fidelity of a class AB amplifier with an efficiency of 91%. It also dramatically reduces solution size by integrating the following: 300mΩ (high side or low side) power MOSFETs (VCC=3.6V), Startup / Shutdown pop elimination, Short circuit protection, 9 Balls Wafer chip scale package (WLCSP) and requires a few external components. This amplifier also improves GSM power supply rejection, and operates on a single cellular Li-ion battery. The gain of this amplifier can be controlled easily by a few modification of external configuration while minimizing noise to 37 μVRMS.
