16-Bit ADCs Achieve High Dynamic Range and Wide Bandwidth, Deliver a New Level of Ease of Use
Applications such as wireless communications, medical imaging, and instrumentation demand ever increasing sampling speeds in combination with higher resolution, superior noise performance, and lower power consumption. Typically, designers must compromise among these requirements. With the advent of continuous time Σ-Δ (CTSD) ADCs, designers can achieve breakthrough performance in their designs without compromising on bandwidth, noise performance, or power consumption, while improving upon ease of use. Utilizing this innovative Σ-Δ converter architecture, ADI's AD926x family of 16-bit CTSD ADCs offers 84.5 dBFS SNR over a dc to 10 MHz bandwidth with a programmable output data rate of 30 MSPS to 160 MSPS. In addition, the unique attributes of the CTSD architecture significantly simplify system level design and help reduce the time to market of the end product. The AD926x CTSD converters employ an easy to drive 1 kΩ resistive input structure, which reduces or eliminates the requirements for a driver amplifier. In addition, a highly oversampled continuous time loop filter architecture attenuates alias components and eliminates the need for external antialiasing filters. Finally, a high dynamic range of 86 dB makes it possible to reduce or eliminate automatic gain control circuitry commonly employed in many communication systems. The result is an ADC that provides system level benefits by reducing component count, cost, power consumption, and design complexity. The AD926x family is available in several different versions including channel count, bandwidth, and level of integration.
*AD9267 is a CTSD modulator providing 4-bit, 640 MSPS LVDS output.
