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 low-cost, all N-channel, synchronous topology enables operation with 93% efficiency.
High-frequency operation allows the use of small inductor and capacitors, resulting in a compact solution.
The MAX1530 includes three linear-regulator controllers and the MAX1531 includes five linear regulator controllers for supplying logic and LCD bias voltages.
A programmable startup sequence provides easy control of the regulators.
The MAX1530/MAX1531 include soft-start functions to limit inrush current during startup.
An internal current-limit function protects the power supplies against fault conditions.
The MAX1530/MAX1531's current-mode control architecture provides fast load-transient response and easy compensation.
An internal linear regulator provides mosfet gate drive and powers small external loads.
The MAX1530/MAX1531 operate from inputs as high as 28V and are ideal for LCD monitor and TV applications running directly from AC/DC wall adapters.
Both devices are available in small (5 x 5mm), ultrathin (0.8mm), 32-pin QFN packages and are specified over the -40 to +85C temperature range.
Prices start at $1.90 for the MAX1530 and $2.20 for the MAX1531 (1000-up, FOB USA).
An evaluation kit is available to speed designs.
