BTL Audio Amplifiers offer up to 1.4W into 4Ω, shutdown mode, and pin-for-pin compatible packaging

What is an iButton?

The MAX9718/MAX9719 fully differential, bridged audio amplifiers ideal for portable audio applications where space is at a premium such as PDAs, cell phones, and smart phones. The MAX9718 is a single-channel amplifier, while the MAX9719 is a dual-channel amplifier for stereo systems. Both devices deliver 1.4W from a single 5V supply into a 4Ω load, and 475mW from a 3V supply into an 8Ω load.

The MAX9718/MAX9719 feature a differential-input structure, offering noise immunity to improve audio reproduction in devices such as cellular phones. The bridge-tied load (BTL) output stage drives the speaker differentially. This provides up to four times the output power of a conventional, single-ended output stage and eliminates the need for output-coupling capacitors, thus minimizing external component count.

The iButton is a computer chip enclosed in a 16mm thick stainless steel can. Because of this unique and durable container, up-to-date information can travel with a person or object anywhere they go. By simply touching the iButton to the two contacts, you can communicate with it through Maxim's 1-Wire protocol. The 1-Wire interface has two communication speeds: standard mode at 16kbps, and overdrive mode at 142kbps.

Each iButton has a unique and unalterable address laser etched onto its chip inside the can. The address (e.g. 2700000095C33108) can be used as a key or identifier for each iButton. The iButton product line comprises over 20 different products with different functionality. iButtons come in the following varieties: Address Only, Memory, Real-Time Clock, Secure and Data Loggers.

The silicon chip within the iButton is protected by the ultimate durable material: stainless steel. You can drop an iButton, step on it, or scratch it. The iButton is wear-tested for 10-year durability.
