PRODUCTION DATA
The ADC356x includes an internal auto-zero front end amplifier circuit which improves the 1/f flicker noise. This auto-zero feature is enabled by default for the ADC3561/2 and can be enabled using SPI register writes for the ADC3563 (register 0x11, D0). The 4M point FFTs below show the autozero feature enabled vs disabled.
