ADI has leading ADC for Digital X-ray
Digital X-Ray
Fine-pitch interconnect geometry (50µm mammography)
Constrained panel thickness (14mm cassette film)
Goal of integrating as much as possible: improve size, cost
Leverage existing technology:
Incorporate die-on-flex packaging
Built-in test for flex/bump/die integrity
Design for thermal management to system level

CT
Channel counts dramatically increasing:16K -> 64K -> 320K ch’s/system System size & cost cannot commensurately increase. IC power, footprint & cost need to be reduced. IC functionality needs to be dramatically increased.
CT– Market and ADI values
Market trend and challenges => ADI’s values:
High slice count => high integration and Low power
Low x-ray dose => low noise and high performance(Low cap, low leakage, low crosstalk)
Shorten the TTM => dedicated expertise provides system level supports and reference design
Lower system cost => completive cost and consistent roadmap

Preamplifier: NF is ~0.2 to 0.3 dB, Gain is ~30 dB, to overcome ADC noise. The preamp will be embedded in the receive coil.
Mixer: Noise floor is very important and spectral purity (especially in-band) is also important. (ADL5801, AD8342)
RF Amplifier: low noise is important, to avoid adding to the ADC noise. VGA (AF8367LF, ADL5201/2, AD8366). ADC driver (ADL5562, ADA4937-1)
ADC: Noise is the most important spec, Spurious performance is not so important. (AD9653, AD9650, AD9446, AD6655, AD6649)
Low phase noise is a must for clocks. (AD9523, ADCLK8xx, ADF4351, ADF4002)

Noise floor is very important for DAC and Mixer Spectral purity (especially in-band) is also important for DAC and Mixer Tx-DAC normally is 16-bit TxDAC, consider AD9779A/AD9788/AD9122 first.
AD9957 DDS more easy of use as more interpolation and easy of control.
Low phase noise is a must for clocks, same source as used for RX (AD9523, ADCLK8xx, ADF4351, ADF4002)
The VGA should below-noise, high-output amp. The PA can put out about 35 kW of RF power

Fitness Monitoring
Pedometer is widely used in home healthcare products, it can work with SpO2, blood pressure, heart rate, respiration rate, etc. to monitor the user fitness everyday, even the sleep quality.
As long as the product is smaller and the requirement on the monitoring time is longer, the built in battery has to be smaller and the system current has to be lower.
ADXL362 has the lowest power consumption on the market and its built in deep FIFO can help to realize system low power, make it very suitable for such applications.
The picture shows the 24/7 activity monitor product from Withings (http://www.withings.com/en/pulse) by using ADXL362.

ADXL362 Applications
User Interface
There are multiply operation modes for consumer products UI, from button to touch and motion recognition. The picture below shows the watch which used ADXL362 to do motion recognition. When user receive the call or email, the watch will vibrate to remind the user, the vibration can be stopped by tapping the watch.
The products like watch has ultra high requirement on current consumption, the lowest power consumption accelerometer ADXL362 is the best for this.
