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 simplicity and robustness of the MAX8535/MAX8536 make them ideal for redundant supplies in high-availability systems, rectifiers, and silver box power supplies in servers and networking applications.
When reverse-current flow through the ORing mosfet is detected, the MAX8535/MAX8536 isolates the failed input supply in less than 1us.
Furthermore, when input under/overvoltage is detected both controllers selectively isolate the faulty supply and maintain a stable bus voltage.
The MAX8535 is suitable for 12V applications, while the MAX8536 is suitable for 3.3 or 5V applications.
Both controllers feature a dual-purpose programmable timer allowing adjustable soft-start or use as a logic enable.
The MAX8535/MAX8536 provide lossless current sensing and offer reverse current protection, as well as adjustable over/undervoltage detection.
Overvoltage, undervoltage, or reverse current conditions are indicated by a versatile fault output.
The MAX8535EUA/MAX8526EUA are available in a space-saving 8-pin microMAX package.
Prices start at $1.50 (1000-up, FOB USA).
Both controllers are specified for the extended-industrial temperature range (-40 to +85C).
An evaluation kit is available to speed designs.
