Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
The MAX8601 is a dual-input charger that automatically selects between either a USB or AC adapter input source.
USB charging (protected by the company's US Patent 6,507,172) is particularly attractive to users of PDAs, smartphones, DSCs and MP3 players, as it frees them from carrying a wall cube.
The MAX8600 and MAX8601 offer up to 14V overvoltage protection at the AC and USB inputs.
Thermal regulation maximises the charging rate under all battery and input voltage conditions.
Charging is optimised for Li+ cells using a control algorithm that includes low-battery precharging, voltage and current-limited fast charging, and top-off charging.
The devices continuously monitor the battery for overvoltage, over-/under-temperature, and charging time.
The charger timeout protection is programmable.
Charger status is indicated by three open drain outputs.
The MAX8600 and MAX8601 are available in space-saving 3 x 3mm, 14-pin TQFN packages and are specified for the extended temperature range from -40 to +85C.
Prices start at $1.25 (1000-up, FOB USA).
An evaluation kit is available to speed designs.
