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.
For 1.5V output applications, the MAX1951 uses small and inexpensive 10uF ceramic input and output capacitors.
Applications include cellular basestations, network and telecomms systems, and set-top boxes.
The MAX1951/MAX1952 integrate power mosfets to reduce the size and complexity of design.
Digital soft-start, current-limit/short-circuit protections, and thermal-overload protection provide for a robust design.
The MAX1951 operates from 2.6 to 5.5V inputs and generates output voltages down to 0.8V with 1% accuracy.
The MAX1952 generates a preset 1.8V output.
Their 1MHz switching frequency reduces the size and cost of external components.
Both devices are compatible with ceramic capacitors.
The MAX1951ESA/MAX1952ESA come in a small 8-pin SO package and prices start at $1.50 (1000-up, FOB, USA).
The MAX1951/MAX1952 are specified for the extended industrial temperature range (-40 to +85C).
Evaluation kits and several application circuits are available to speed designs.
