The KAD5612P is a family of low-power, high-performance,
dual-channel 12-bit, analog-to-digital converters. Designed
with FemtoCharge™ technology on a standard CMOS process,
the family supports sampling rates of up to 250MSPS. The
KAD5612P-25 is the fastest member of this pin-compatible
family, which also features sample rates of 210MSPS
(KAD5612P-21), 170MSPS (KAD5612P-17) and 125MSPS
(KAD5612P-12).
Features
• Programmable gain, offset and skew control
• 1.3GHz 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 gain, skew and offset
matching between the two converter cores.
• 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 KAD5612P is available in a 72 Ld QFN package
with an exposed paddle. Performance is specified over the full
industrial temperature range (-40°C to +85°C).
