KAD5512P
FN6807.2
Low Power 12-Bit, 250/210/170/125MSPS
ADC
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
pin-compatible portfolio of 10, 12 and 14-bit A/Ds with
sample rates ranging from 125MSPS to 500MSPS.
A serial peripheral interface (SPI) port allows for extensive
configurability, as well as fine control of various parameters
such as gain and offset.
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).
Key Specifications
• SNR = 66.1dBFS for f_IN = 105MHz (-1dBFS)
• SFDR = 87dBc for f_IN = 105MHz (-1dBFS)
• Total Power Consumption
- 267/219mW @ 250/125MSPS (SDR Mode)
- 234/189mW @ 250/125MSPS (DDR Mode)
