AD9480: 8-Bit, 250 MSPS 3.3V A/D Converter Data Sheet (Rev. A)7/1/2004845 kB
Features and Benefits
- DNL = ±0.25 LSB
- INL = ±0.5 LSB
- Single +3.3 V supply operation (3.0 to 3.6 V)
- Power dissipation of 590 mW at 250 MSPS
- 1 Vp-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
The AD9480 is an 8-bit monolithic analog-to-digital converter optimized for high speed, low power, small size, and ease of 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 components are required for many applications.
The digital outputs are LVDS (ANSI 644) compatible with an option of twos complement 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 BiCMOS process, the AD9480 is available in a 44-pin surface mount package (TQFP) specified over the industrial temperature range (-40°C to +85°C).
- Superior linearity. A DNL of ±0.25 makes the AD9480 suitable for instrumentation and measurement applications.
- Power-down mode. A power-down function may be exercised to bring total consumption down to 15 mW.
- LVDS outputs (ANSI-644). LVDS outputs simplify timing and improve noise performance.
- Digital oscilloscopes
- Instrumentation and measurement
