MAX9890BETA+T

MAX9890BETA+T is Maxim’s beta evaluation kit and reference design for the MAX9890, a high‑efficiency Class‑D audio amplifier. It provides a ready‑to‑use board and documentation to quickly evaluate the device in stereo, single‑supply audio systems common in automotive and consumer electronics. The kit demonstrates key capabilities such as differential inputs, Class‑D PWM outputs, built‑in protections (short‑circuit, over‑current, thermal), mute/standby control, and straightforward system integration. It also exposes test points and layout guidance to optimize EMI, THD+N, and efficiency. The “+T” denotes a specific PCB revision of the kit. Use the board to measure performance metrics (THD+N, SNR, efficiency), explore filter/topology options, and validate in your target enclosure. As a beta product, consult the latest MAX9890 datasheet and user guide for exact specs, limitations, and setup steps.

I need the chip function to propose equivalents. MAX9890BETA+T isn’t enough; is it a Maxim audio amplifier IC? Please specify: function (amp/DAC/ADC), number of channels, supply (Vcc), interface (I2C/SPI), package, power output. With that I can provide cross-refs from TI, Analog Devices, Onsemi, NXP.

Analog Devices, Inc. (ADI). It is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits. (MAX9890BETA+T was originally from Maxim Integrated, which is now part of ADI.)

Applications include high-efficiency stereo audio amplification for portable and compact consumer electronics, such as:
- Smartphones, tablets, portable media players
- Portable Bluetooth speakers and smart speakers
- USB audio docks and multimedia adapters
- TV soundbars and other small home theater/audio systems

"BETA" is Maxim's internal package code for the MAX9890; "+T" denotes tape-and-reel shipping. For the exact physical package family, dimensions, and pin count, refer to the MAX9890 datasheet/mechanical drawing.
