Its 40 MSPS operation makes it suitable for a variety of high-speed, medium-bandwidth applications. The AD9280ARSZRL features an on-chip differential PGA, flexible LVDS 12-bit output format and an integrated input buffer that significantly reduces the number of components required for applications such as receivers and secure communications. The AD9280ARSZRL is designed to meet a wide range of data acquisition and imaging requirements, with excellent dynamic performance and low-power consumption.

Application Field

The AD9280ARSZRL is an ideal solution for high-speed analog data acquisition and imaging applications. It can be used in a variety of applications, such as medical imaging, communications, radar, and audio. It is able to perform 12-bit conversions at up to 40 MSPS, making it suitable for medium to high-bandwidth applications. It is also ideal for low-noise and low-power applications, making it an excellent choice for applications such as receivers or secure communications.

Working Principle

The AD9280ARSZRL works by digitizing analog input signals, then applying an analog-to-digital conversion algorithm to represent the digital values of the analog input. It uses an on-chip differential PGA for programmable gain adjustment, with an adjustable full-scale input range up to 4.096V. The differential input buffer on-chip reduces the amount of external components required for the application. The conversion algorithm is based on a twos complement technique, with successive approximation register and DAC architecture. A digital filter is used to further reduce the output noise.

The AD9280ARSZRL features an LVDS output format that allows data rates up to 40 megasamples per second. It is ideal for applications requiring high dynamic performance, with a maximum conversion speed of 2.5 microseconds, minimum (−20 dBFS) signal-to-noise ratio of 79 dB, and differential linearity error of 1 LSB. The unit is also designed for low-power operation, with a total core power of only 1.3W.
