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.
It integrates all switches (power switch, synchronous rectifier, and reverse current blocker) allowing for use in size-constrained hand-held equipment.
It also features True Shutdown, which allows the load to be discharged and disconnected from the battery during shutdown to maximise battery life.
The MAX1947 accepts low inputs (0.7V) and delivers low outputs (1.8V).
It offers fixed output options that eliminate an external feedback network, further reducing the component count.
Its automatic pulse-skipping at light loads extends battery life.
The MAX1947 is available in a space-saving 3 x 3mm 8-pin thin DFN package screened for the extended temperature range (-40 to +85C).
Prices start at $1.55 (1000-up, FOB USA).
The MAX1947EVKIT evaluation kit is available to speed designs.
