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 small size and minimal external part count is ideal for smart phone and PDA applications.
The MAX1572 operates at a high 2MHz and provides precision line and load regulation for the latest CPU and DSP cores.
It uses a low-profile 2.2uH inductor and tiny ceramic capacitors.
It has an input range of 2.6 to 5.5V for use with a single lithium-ion battery.
Other features include voltage positioning for excellent load transients and analogue soft-start with zero inrush current.
To maximise battery life for handheld equipment, the quiescent current is only 48uA and drops to 0.1uA in logic-controlled shutdown.
The MAX1572 comes in a space-saving 12-pin QFN package and is screened for the extended-industrial temperature range (-40 to +85C).
Prices start at $1.95 (1000-up, FOB USA).
An evaluation kit is available to speed designs.
