Overview

DNL = ±0.35 LSB
INL = ±0.26 LSB
Single 3.3 V supply operation (3.0 V to 3.6 V)
Power dissipation of 439 mW at 250 MSPS
1 V p-p analog input range

Internal 1.0 V reference
Single-ended or differential analog inputs
De-multiplexed CMOS outputs
Power-down mode
Clock duty cycle stabilizer

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

Superior linearity. A DNL of ±0.35 makes the AD9481 suitable for many instrumentation and measurement applications
Power-down mode. A power-down function may be exercised to bring total consumption down to 15 mW.
De-multiplexed CMOS outputs allow for easy interfacing with low cost FPGAs and standard logic.

Applications

Digital oscilloscopes
Instrumentation and measurement
Communications:
Point-to-point radios
Digital predistortion loops

Product Details

The high speed ADC FIFO evaluation kit includes the latest version of ADC Analyzer and a buffer memory board to capture blocks of digital data from the Analog Devices, Inc., high speed analog-to-digital converter (ADC) evaluation boards. The FIFO board is connected to the PC through a USB port and is used with ADC Analyzer to quickly evaluate the performance of high speed ADCs. Users can view an FFT for a specific analog input and encode rate to analyze SNR, SINAD, SFDR, and harmonic information.

The evaluation kit is easy to set up. Additional equipment needed includes an Analog Devices high speed ADC evaluation board, a signal source, and a clock source. Once the kit is connected and powered, the evaluation is enabled instantly on the PC.

The HSC-ADC-EVALB-DCZ can be used with single and multichannel ADCs and converters with demultiplexed digital outputs.
