Low Power 12-Bit, 250/210/170/125MSPS
ADC
Features
• Pin-Compatible with the KAD5512HP Family, Operating at
Half the Power
The KAD5512P is the low-power member of the KAD5512
family of 12-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 KAD5512P is part of a
• Programmable Gain, Offset and Skew Control
• 1.3GHz Analog Input Bandwidth
• 60fs Clock Jitter
pin-compatible portfolio of 10, 12 and 14-bit A/Ds with
sample rates ranging from 125MSPS to 500MSPS.
• 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
Digital output data is presented in selectable LVDS or CMOS
formats. The KAD5512P is available in 72- and 48-contact
QFN packages with an exposed paddle. Operating from a
1.8V supply, performance is specified over the full industrial
temperature range (-40°C to +85°C).
• Two’s Complement, Gray Code or Binary Data Format
• SDR/DDR LVDS-Compatible or LVCMOS Outputs
• Programmable Built-in Test Patterns
• Single-Supply 1.8V Operation
• Pb-Free (RoHS Compliant)
