Low Power 12-Bit, 250/210/170/125MSPS ADC
KAD5512P
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 fIN = 105MHz (-1dBFS)
SFDR = 87dBc for fIN = 105MHz (-1dBFS)
Total Power Consumption
- 267/219mW @ 250/125MSPS (SDR Mode)
- 234/189mW @ 250/125MSPS (DDR Mode)
