AFE5809 - Fully Integrated, 8 Channel Analog Front End with Passive CW Mixer & Digital I/Q Demodulation for Sonar and Ultrasonic Non-Destructive Testing

Click to enlarge

The AFE5809 is a highly integrated analog front end (AFE) solution specifically designed for ultrasound systems in which high performance and small size are required. The AFE5809 integrates a complete time-gain-control (TGC) imaging path and a continuous wave Doppler (CWD) path. It also enables users to select one of various power/noise combinations to optimize system performance. Therefore, the AFE5809 is a suitable ultrasound analog front end solution not only for high-end systems, but also for portable ones. AFE5809 also includes a digital in-phase and quadrature (I/Q) demodulator and a low-pass decimation filter. The main purpose of the demodulation block is to reduce the LVDS data rate and improve overall system power efficiency.

ADS5295 - Octal Channel 12-Bit, 100MSPS High-SNR and Low-Power ADC for Phased Array Architecture Radar, Sonar, and CCD Image Sensor Conditioning

The ADS5295 is a low-power, 12-bit, 100-MSPS, 8-channel analog-to-digital converter (ADC). Low power consumption and integration of multiple channels in a compact package make the device attractive for very high channel count data acquisition systems. The device integrates an internal reference trimmed to accurately match across devices. Best performance is expected to be achieved through the internal reference mode. However, the device can be driven with external references as well. Several digital functions that are commonly used in systems are included in the device. These functions include a low-frequency suppression mode, digital filtering options, and programmable mapping.

ADS5263 - Quad Channel 16-Bit, 100-MSPS 84.6dB SNR ADC for CCD Image Sensor Conditioning

Using CMOS process technology and innovative circuit techniques, the ADS5263 is designed to operate at low power and give very high SNR performance with a 4-Vpp full-scale input. Using a low-noise 16-bit front-end stage followed by a 14-bit ADC, the device gives 85-dBFS SNR up to 10 MHz and better than 80-dBFS SNR up to 30 MHz. The ADS5263 has a digital processing block that integrates several commonly used digital functions, such as digital gain (up to 12 dB). It includes a digital filter module that has built-in decimation filters (with low-pass, high-pass and band-pass characteristics). The decimation rate is also programmable (by 2, by 4, or by 8). This makes it very useful for narrow-band applications, where the filters can be used to improve SNR and knock-off harmonics, while at the same time reducing the output data rate.

DDC264 - 64-Channel, Current-Input Analog-to-Digital Converter for Security X-ray and X-ray based Non-Destructive Testing

Click to enlarge

The DDC264 is a 20-bit, 64-channel, current-input ADC. It combines both current-to-voltage and A/D conversion so that 64 separate low-level current output devices, such as photodiodes, can be directly connected to its inputs and digitized. For each of the 64 inputs, the DDC264 uses the proven dual switched integrator front-end. This configuration allows for continuous current integration: while one integrator is being digitized by the onboard ADC, the other is integrating the input current. This architecture provides both a very stable offset and a loss-less collection of the input current. Adjustable integration times range from 160µs to 1s, allowing currents from fAs to µAs to be continuously measured with outstanding precision.

AFE0064 - 64 Channel Analog Front End for Digital Security X-ray and X-ray based Non-Destructive Testing

The AFE0064 is a 64 channel AFE designed to suit the requirements of flat panel detector based digital X-ray systems. The device includes 64 integrators, a PGA for full scale charge level selection, correlated double sampler, 64 as to 2 multiplexer, and two differential output drivers. Hardware selectable integration polarity allows integration of a positive or negative charge and provides more flexibility in system design. In addition, the device features TFT (Thin Film Transistor from Flat Panel Detector) charge injection compensation. This feature helps maximize the usable signal charge range of the device.
