Low Power 10-Bit, 250/210/170/125MSPS ADC
KAD5510P
Features
The KAD5510P is a family of low power, high performance 10-bit
analog-to-digital converters. Designed with Intersil’s proprietary
FemtoCharge™ technology on a standard CMOS process, the
family supports sampling rates of up to 250MSPS. The
KAD5510P is part of a pin-compatible portfolio of 10, 12 and
14-bit A/Ds with sample rates ranging from 125MSPS to
500MSPS.
• 1.5GHz Analog Input Bandwidth
• 60fs Clock Jitter
• Programmable Gain, Offset and Skew Control
• Over-Range Indicator
• Selectable Clock Divider: ÷1, ÷2 or ÷4
• Clock Phase Selection
A serial peripheral interface (SPI) port allows for extensive
configurability, as well as fine control of various parameters such
as gain and offset.
• Nap and Sleep Modes
• Two’s Complement, Gray Code or Binary Data Format
• DDR LVDS-Compatible or LVCMOS Outputs
• Programmable Built-in Test Patterns
• Single-Supply 1.8V Operation
• Pb-Free (RoHS Compliant)
Digital output data is presented in selectable LVDS or CMOS formats.
The KAD5510P is available in a 48-contact QFN package with an
exposed paddle. Operating from a 1.8V supply, performance is
specified over the full industrial temperature range (-40°C to +85°C).
