AD9480 Datasheet | Analog Devices

Features DNL = ± 0.25 LSB INL = ± 0.26 LSB Single 3.3 V supply operation (3.0 V to 3.6 V) Power dissipation of 590 m W at 250 MSPS 1 V p-p analog input range Internal 1.0 V reference Single-ended or differential analog inputs LVDS outputs (ANSI 644 levels) Power-down mode Clock duty-cycle stabilizer APPLICATIONS Digital oscilloscopes Instrumentation and measurement munications Point-to-point radios Predistortion loops GENERAL DESCRIPTION The AD9480 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 AD9480 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 ponents are required for many applications. The digital outputs are LVDS (ANSI 644) patible with an option of twos plement or binary output format. The output data bits are provided in parallel fashion along with an LVDS output clock, which simplifies data capture. Fabricated on an advanced Bi CMOS process, the AD9480 is available in a 44-lead surface-mount package (TQFP) specified over the industrial temperature range - 40°C to +85°C. 8-Bit, 250 MSPS 3.3 V A/D Converter FUNCTIONAL BLOCK DIAGRAM VREF SENSE AGND Dr GND DRVDD AVDD REFERENCE VIN+ VIN- T&H 8-BIT ADC PIPELINE CORE LVDS D7- D0 (LVDS) CLK+ CLK- CLOCK MGMT LOGIC DCO+ DCO(LVDS) 04619-001 PDWN S1 LVDSBIAS Figure...
