The SSM6515 is one of the smallest and lowest-power amplifiers available on the market.
BRAD6515 was created out of the need for a smaller, more handy, and cheaper breakout board than the Analog Devices Evaluation Board.
It was designed to maintain the configuration options offered by the EVB but removing some parts that were not essential for its operation.
The module is stereo, with two SSM6515 amplifiers.
The PCB has two 2.54mm pitch 8-pin connectors, compatible with classic breadboards and allowing for quick and easy connection.
The main power supply is 5V (VIN), while the reference voltage for I2C/I2S can be set to 1.8V or 3.3V (VIO).
There are two level translators on board to ensure proper operation and voltage compatibility with the external host.
To slightly simplify the design, the amplifier supply voltage has been set to 1.8V for both PVDD and IOVDD.
Thanks to the soldered jumpers, it is possible to change the operating mode of the amplifiers.
The power rails of the two amplifiers have been separated and sectioned using jumpers; this is to allow for more detailed consumption measurements.
