Dual Differential ADC Drivers Claim Industry First

Pledging to reduce design complexity, cost, and board space, the ADA4937-2 and ADA4938-2 are described as the industry's first dual differential ADC drivers. In principle, the devices enhance key performance characteristics, i.e., SFDR and SNR, of ADCs operating from dc to 100 MHz. In terms of performance, the ADA4937-2 achieves distortion figures of -120/-102 dBc at 10 MHz, -98/-100 dBc at 40 MHz, and -84/-90 dBc at 70 MHz while the ADA4938-2 specifies -112/-108 dBc at 10 MHz, -96/-93 dBc at 30 MHz, and -79/-81 dBc at 50 MHz. Shared features include a common-mode feedback architecture and proprietary SiGe complementary bipolar process technology. Sampling now with full production scheduled for October, price is $5.69 each/1,000. ANALOG DEVICES INC., Norwood, MA. (800) 262-5643.
