The ADI Chinese version datasheet is a translation of the English version datasheet, introducing the features and characteristics of the filterless, high-efficiency, single-channel 2.5 W D-class audio amplifier.
The SSM2377 is a highly integrated, high-efficiency Class-D audio amplifier designed for mobile phone applications. It features a filterless design with low EMI radiation, high power supply rejection ratio, and pop-and-click suppression. The device operates with a single power supply ranging from 2.5 V to 5.5 V and supports gain settings of 6 dB or 12 dB. This manual is written in Chinese.
| Output Power (8 Ω, 1 kHz, 1% THD) | 1.41 W at 5.0 V |
|---|---|
| Signal-to-Noise Ratio | >100 dB |
| Power Supply Rejection Ratio | 80 dB |
| Input Impedance | 80 kΩ |
| Shutdown Current | 100 nA |
| Operating Temperature Range | -40°C to +85°C |
| Package Type | 9-pin 1.2 mm x 1.2 mm WLCSP |
The device supports a single power supply ranging from 2.5 V to 5.5 V.
The gain can be configured for either 6 dB or 12 dB by connecting the GAIN pin to VDD or GND.
The shutdown current is 100 nA typical when the SD pin is pulled low.
