Maxim Integrated Products MAX11040: Simultaneously sampling ADC enables daisy-chaining of as many as eight devices

The four-channel, 24-bit simultaneously sampling MAX11040ADC allows daisy-chaining of as many as eight devices, providing a 32-channel-sampling capacity. The converter provides cascade SPI, QSPI, and Microwire interfaces. Featuring a minimum of 90 dB of SINAD and 91-dB of SFDR, the device aims at industrial power-grid-protection equipment, medical EKG/EEG equipment, and applications requiring accurate conversion of simultaneously sampled channels between 0.25k and 64k samples/sec. The converter provides overvoltage protection against ±6V voltages. Available in a TSSOP-38, the ADC costs $13.45 (1000).
