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.
This family of high-performance ADCs includes the MAX1213 (12bit, 170Msample/s), MAX1122 (10bit, 170Msample/s), MAX1123 (10bit, 210Msample/s), MAX1124 (10bit, 250Msample/s) and MAX1121 (8bit, 250Msample/s).
These convertors offer exceptional dynamic performance at high input frequencies.
They provide unmatched dynamic performance, including signal/noise ratio (SNR), spurious-free dynamic range (SFDR), and intermodulation distortion (IMD).
They consume the lowest power in their class.
The 12bit MAX1213 offers a SNR of 65.5dB that remains flat (within 1.5dB) up to 250MHz input frequency.
The MAX1213 also has an industry-leading noise/power ratio (NPR) of 62dB, which is better than the closest competitor by 3dB and consumes 30% less power.
At the 10bit level, the MAX1123 delivers an exceptional SNR of 57.5dB that remains flat (within 1.5dB) up to 500MHz input frequency, more than 2dB higher than the competition.
This superior dynamic performance is even more remarkable given the low power consumption of less than 500mW at sample rates up to 250Msample/s, an industry first.
At the 8bit level, the MAX1121 delivers an SNR of 48.8dB (2.8dB better than the competition) and an SFDR of 68dBc (8dB better than the competition).
Differential nonlinearity is similarly impressive at +0.1LSB.
The combination of high-IF dynamic performance and high sample rate allows the user to select receiver architectures that can sample large bandwidths while eliminating intermediate, RF down-conversion stages.
This design flexibility reduces system cost and complexity, and saves board space.
The MAX1213, MAX1122, MAX1123, MAX1124 and MAX1121 are ideal for applications such as cable and cellular infrastructures, broadband-communication systems, instrumentation and high-performance video equipment.
These devices are available in space-saving 68-pin QFN-EP packages specified for the extended temperature range (-40 to +85C).
Prices start at $23.85 (1000-up, FOB USA).
An evaluation kit is available to speed designs.
