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 MAX8620Y's integration saves space and cost powering the microprocessor in portable equipment where efficiency and total solution size are critical.
Applications for the MAX8620Y include cellphones, smartphones and MP3 players.
The tiny TDFN package saves 78% of the space required by alternative designs.
Typical alternative solutions use separate ICs that occupy 41mm2.
Providing up to 92% efficiency, the 4MHz synchronous step-down DC/DC convertor uses a low-profile 1uH inductor and tiny ceramic capacitors.
Its fast, 100ns transient response fits demanding processor applications like graphics processing, video streaming and gaming.
The two LDOs provide low-noise 45uV RMS output, and their output voltages are pin-programmable to save size and maintain flexibility.
The reset output warns the system of impending power loss, thereby allowing safe shutdown.
The MAX8620Y is available in a space-saving 3 x 3mm, 14-pin TDFN package, screened for the extended-industrial temperature range (-40 to +85C).
Prices start at $2.20 (2500-up, FOB USA).
The MAX8620YEVKIT (evaluation kit) is available to speed designs.
