●Product Details
●The AD9481 is an 8-bit, monolithic analog-to-digital converter (ADC) optimized for high speed and low power consumption. Small in size and easy to use, the product operates at a 250 MSPS conversion rate, with excellent linearity and dynamic performance over its full operating range.
●To minimize system cost and power dissipation, the AD9481 includes an internal reference and track-and-hold circuit. The user only provides a 3.3 V power supply and a differential encode clock. No external reference or driver components are required for many applications.
●The digital outputs are TTL/CMOS-compatible with an option of twos complement or binary output format. The output data bits are provided in an interleaved fashion along with output clocks that simplifies data capture.
●The AD9481 is available in a Pb-free, 44-lead, surface-mount package (TQFP-44) specified over the industrial temperature range (−40°C to +85°C).
●Product Highlights
● 1. Superior linearity. A DNL of ±0.35 makes the AD9481 suitable for many instrumentation and measurement applications
● 2. Power-down mode. A power-down function may be exercised to bring total consumption down to 15 mW.
● 3. De-multiplexed CMOS outputs allow for easy interfacing with low cost FPGAs and standard logic.
