16-Bit, 210Msps ADC delivers 80dB SNR

Mon, 04/28/2014 - 2:13pm

Linear Technology Corporation (Milpitas, CA) announces the LTC2107, a 16-bit 210Msps high performance high-speed analog-to-digital converter (ADC) for high-end communications receivers and instrumentation applications. The LTC2107 has superior AC performance specifications, achieving 80dB SNR performance, 4dB higher than alternative products, and industry leading 98dB SFDR at baseband. Exceptional aperture jitter of only 45fsRMS enables direct sampling of frequencies up to 500MHz with excellent SNR performance. Other features include:

• An optional internal transparent dither circuit, which improves the ADC’s SFDR response well beyond 100dBFS for low-level input signals.
• Digital output randomizer and alternate bit polarity mode, which dramatically reduce unwanted tones caused by digital feedback.
• A programmable gain amplifier (PGA) front end that sets the ADC input range to either 2.4VP-P or 1.6VP-P.
• Distortion performance achieved in the 1.6VP-P range while the 2.4VP-P range results in the best noise performance.
