16-Bit Data Converters
Analog Devices introduces two ADCs targeted for high-end instrumentation, medical and wireless communications applications that enable designers to maintain low noise and high dynamic range, even at high input frequencies. Designers of medical systems, such as magnetic resonance imaging and patient monitoring receivers will benefit from the converters which offer a high signal to noise ratio (SNR) at 79 dB. The AD9460 and AD9461 provide 16-bit performance up to 130 MSPS (mega samples per second), enabling the high dynamic range required for signal analysis, radar, magnetic resonance imaging (MRI), and multi-carrier/multi-std wireless communications systems. Both devices include an integrated input buffer to isolate the ADC input, eliminating the need for external buffering that can consume up to 1 W of power, thereby easing the driving of the ADC, whether driven by transformers or amplifiers.
