FN6808.0
High Performance 12-Bit,
Features
250/210/170/125MSPS ADC
• Pin-Compatible with the KAD5512P Family, Offering
2.5dB Higher SNR
The KAD5512HP is the high-performance 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
KAD5512HP is part of a pin-compatible portfolio of 10, 12
and 14-bit A/Ds with sample rates ranging from 125MSPS to
500MSPS.
• Programmable Gain, Offset and Skew control
• 950MHz Analog Input Bandwidth
• 60fs Clock Jitter
• 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 KAD5512HP 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).
