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 MAX5858 also features digital control of channel gain matching to within +/-0.4dB in 16 steps of 0.05dB.
Specified over the 2.7 to 3.3V operating range and an extended output compliance voltage, the MAX5858 delivers outstanding dynamic performance.
At a 20MHz output frequency (165MHz sample rate), the spurious-free dynamic range (SFDR) is 75dBc.
The adjacent channel leakage ratio (ACLR) is 69dBc when the output frequency is 30.7MHz (3.8MHz channel).
The integrated interpolation filters, which separate the generated images, make the analogue filter following the DAC cost effective and easy to design.
In addition, the interpolation filters lower the input datarate and reduce the inherent DAC rolloff.
The combination of excellent performance and onboard interpolation filters makes the MAX5858 ideal for communication systems such as point-to-point microwave links, LMDS, MMDS, WLAN basestations and VSAT terminals.
The MAX5858 is the lead product in a family of high-performance DACs.
The MAX5858 is available in a space-saving 48-pin TQFP package specified for the industrial temperature range (-40 to +85C).
Prices start at $11.80 (1000-up, FOB USA).
An evaluation kit is available to speed designs.
