KAD5612P
FN6803.2
Dual 12-Bit, 250/210/170/125MSPS A/D
Converter
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).
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.
Digital output data is presented in selectable LVDS or CMOS
formats. The KAD5612P is available in a 72-contact QFN
package with an exposed paddle. Performance is specified
over the full industrial temperature range (-40°C to +85°C).
