PRODUCTION DATA
AC PSRR measures the ability of a device to prevent noise and spurious signals that appear on the supply voltage pin from coupling to the output of the switch. The DC voltage on the device supply is modulated by a sine wave of 620mVPP. The ratio of the amplitude of signal on the output to the amplitude of the modulated signal is the AC PSRR. Figure 7-13 shows the setup used to measure ACPSRR of the TMUX6119.
