Maxim MAX19527 ultra-low-power 12-bit 50 Msps ADC

Maxim has introduced the MAX19527, an ultra-low-power, 12-bit, 50 Msps ADC optimised for portable ultrasound systems.

Integrating 8-channels on a single chip, the ADC operates from a single 1.8 V supply and consumes 55 mW per channel. Unused ADC channels can be powered down to further reduce power consumption.

Good dynamic performance (69 dBFS broadband SNR at 5.3 MHz and 140 dBc/Hz near-carrier SNR at 1 kHz offset from a 5.3 MHz tone) allows good image quality and sensitivity in all imaging modes. The device delivers big-machine ultrasound image quality with a PCB footprint and power budget optimised for portable systems.

A serial LVDS interface and programmable adjustments and feature selection maximises system flexibility for high-end or portable medical imaging uses.
