High Performance 12-Bit,
250/210/170/125MSPS ADC
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.
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 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).

... Theory of Operation Functional Description The KAD5512HP is based upon a 12-bit, 250MSPS A/D converter core that utilizes a pipelined successive approximation architecture (Figure 21). The input voltage is captured by a Sample-Hold Amplifier (SHA) and converted to a unit of charge. Proprietary charge-domain techniques are used to successively compare the input to a series of reference charges ...

... OVDD the case during power-on reset, the SDO, RESETN and DNC pins must be in the proper state for the calibration to successfully execute. The performance of the KAD5512HP changes with variations in temperature, supply voltage or sample rate. The extent of these changes may necessitate recalibration, depending on system performance requirements ...

... VCM. The value of the shunt resistor should be determined based on the desired load impedance. The differential input resistance of the KAD5512HP is 500Ω. The SHA design uses a switched capacitor input stage (see Figure 41), which creates current spikes when the sampling capacitance is reconnected to the input voltage ...

... The OR bit is updated at the sample rate. Power Dissipation The power dissipated by the KAD5512HP is primarily dependent on the sample rate and the output modes: LVDS vs CMOS and DDR vs SDR. There is a static bias in the analog supply, while the remaining power dissipation is linearly related to the sample rate ...
