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.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
The MAX8685C and MAX8685D are the industry's smallest xenon photoflash capacitor chargers that include an integrated switching FET and IGBT driver.
Due to a fast charge time and small size, the various versions of the MAX8685 are ideal for compact and single-lens reflex (SLR) digital still cameras (DSCs), film cameras, mobile phone cameras, web cameras or personal media players.
Having a programmable current limit of up to 2.6A, the MAX8685F can charge a 100uF capacitor to 300V in two seconds.
Its resistor-programmable current limit allows for one version of the part to be used across a platform requiring various current-limit settings.
The MAX8685F provides a scaled replica of the output voltage to a microprocessor to aid red-eye reduction.
An additional input voltage monitoring feature provides added flexibility by automatically reducing the current limit at low battery voltages for the fastest charge rate under any battery conditions.
Other MAX8685 advantages include an autorefresh mode, no inrush current, short-circuit protection, open-capacitor protection and a robust architecture that allows the use of low-cost transformers.
The MAX8685F is available in a tiny 3 x 3mm, 14-pin TDFN package.
The MAX8685C and MAX8685D, which do not include a voltage monitor or input-voltage monitoring, are available in a 2 x 3mm, eight-pin TDFN package.
