The LTC2299 is a dual CMOS pipelined multi-step analog-to-digital converter. The converter has six pipelined ADC stages; a sampled analog input will result in a digitized value six cycles later. It operates on a 3V supply and the parallel CMOS output logic can be reduced to as low as 0.5V for low voltage processors or FPGAs. At just 444mW, or 222mW per channel, the LTC2299 consumes less power than even slower competitors. It has excellent AC performance, achieving 73dB Signal-to-Noise Ratio (SNR) and 90dB Spurious Free Dynamic Range (SFDR) at 70MHz.

For higher input frequencies, it continues to excel with 72.6dB SNR and 80dB SFDR up to 140MHz. Channel-to-channel isolation is better than 110dB from low frequency all the way up to 100MHz. Optimized for undersampling with wide bandwidth, it suits single-carrier and multi-carrier base station designs that need multiple receive channels in a small area. The small 9mm x 9mm QFN package makes this dual ADC ideal for medical imaging, instrumentation and communications applications.
