Health care diagnostic imaging devices, from customary prenatal care to advanced cardiac imaging equipment, are increasingly expected to provide more precise images, while also becoming more portable. To meet these demands, Texas Instruments has introduced the AFE5818 and AFE5816 families, which are claimed to be the industry’s first 16-channel ultrasound AFEs.
The AFEs integrate a range of features to maximise image quality and performance while minimising power consumption and system cost. To optimise system efficiency, these families offer multiple versions with and without a demodulation block and JESD204B interface option, which further simplifies board layout and provides cost savings. The families also offer industry-leading low power consumption for the noise performance achieved, enabling portable solutions that offer better imaging performance without negatively impacting the power budget.
Key features and benefits:
Complementing the AFE5818 and AFE5816 families is TI’s ADS52J90, a new 16-channel high-speed ADC that can be configured for up to 32 inputs, for ultrasound receiver designs that require greater front end design flexibility. The ADC also offers the on-chip digital demodulator for reducing processor or FPGA costs, as well as a LVDS or JESD204B serial interface for faster data rates.
TI offers EVMs for the AFE5818, AFE5816 and ADS52J90 families for quick and easy evaluation. The AFE5818EVM, AFE58JD18EVM and AFE58JD16EVM are priced at $599, and the ADS52J90EVM is priced at $1,249. All EVMs are available from the TI store and authorised distributors.
The AFE5818 and AFE5816 families and ADS52J90 are all available today. Pricing in 1,000 unit quantities starts from $130 each.
