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.
Devices in this high-performance ADC family have been optimised for baseband and direct-IF (intermediate frequency) sampling applications.
They include the MAX12553 (14bit, 65Msample/s, baseband/IF), MAX1209 (12bit, 80Msample/s, IF), MAX1211 (12bit, 65Msample/s, IF), MAX1208 (12bit, 80Msample/s, baseband), MAX1207 (12bit, 65Msample/s, baseband), and MAX1206 (12bit, 40Msample/s, baseband).
These ADCs are ideal for applications such as communication receivers, medical imaging, portable instrumentation and low-power data acquisition.
The MAX12553, MAX1209 and MAX1211 deliver exceptional dynamic performance at input frequencies up to 400MHz, making them suitable for direct-IF sampling applications.
For example, the MAX12553 delivers 70.9dB SNR and 80.7dBc SFDR at an input frequency of 175MHz, while consuming only 363mW of power.
The direct-IF sampling capability of these ADCs eliminates the need for down-conversion stages, which simplifies system design, lowers cost, reduces power, and saves board space.
For baseband sampling applications, the MAX12553, MAX1208, MAX1207 and MAX1206 deliver exceptional dynamic performance up to Nyquist frequency.
The MAX1208, for example delivers 68.2dB SNR and 88.2dBc SFDR at an input frequency of 32.5MHz, while consuming only 399mW of power.
All the 14 and 12bit devices are pin compatible.
This allows additional design flexibility by enabling the designer to migrate to higher or lower levels of performance with minimal changes.
These devices are available in space-saving, 40-pin, thin QFN-EP packages specified for the extended temperature range (-40 to +85C).
Prices start at $24.85 for the 14bit ADC family and $8.95 for the 12bit ADC family (1000-up, FOB USA).
Evaluation kits are available to speed designs.
