Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).

The MAX98357 digital input Class-D audio power amplifier helps designers achieve compact, efficient, and plug-and-play solutions at a high cost-performance ratio. In addition to its small form factor, the device delivers 3.2W of Class-AB amplifier sound quality with Class-D amplifier efficiency, providing excellent high-fidelity audio suitable for a wide range of applications. The MAX98357 Pulse Code Modulation (PCM) and MAX98358 Pulse Density Modulation (PDM) plug-and-play speaker amplifiers fully leverage the flexibility of Maxim's pinout. Compared to typical analog amplifier solutions, this significantly reduces component count, resulting in a substantial reduction in solution size. Since most users control volume digitally, these features allow users to fully utilize Maxim's cost-effective wafer-level package (WLP) without the need for expensive PCBVIA. For superior sound quality, the device employs highly noise-immune digital inputs and offers high jitter tolerance (at least 8dB better than competing solutions). The device also provides excellent electromagnetic interference (EMI) suppression, allowing for long-wire speaker connections without the need for external filtering. Furthermore, the device offers industry-leading Class-D efficiency.
Output Power
3.2W at 4Ω, THD 10%
1.8W at 8Ω, THD 10%
I2S Sampling Rate: 8kHz-96kHz
Class D Amplifier, Selectable Gain: 3dB/6dB/9dB/12dB/15dB, No Master Clock (MCLK) Required
Plug and Play: Requires only a single power supply and automatically configures 35 different clocks and 128 digital audio formats. Compatible with microcontrollers or development boards with I2S audio output, such as Raspberry Pi, Arduino, and ESP32.
Pin Descriptions
LRC: Left/Right clock for 12S and LJ modes. Synchronous clock is used in TDM mode.
BCLK: Bit clock input
DIN: Digital input signal
GAIN: Gain and channel selection. In TDM mode, the gain is fixed at 12dB
SD: Power off and channel selection. Pulling SD MODE low puts the device in the power-off state.
GND: Power ground
VCC: Positive power supply, DC 2.5V-5.5V
