8.1.11 AC Power Supply Rejection Ratio (AC PSRR)
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 620 mVPP. The ratio of the amplitude of signal on the output to the amplitude of the modulated signal is the AC PSRR. Figure 8-11 shows the setup used to measure ACPSRR of the TMUX6121, TMUX6122, and TMUX6123.
Figure 8-11 AC PSRR Measurement SetupSection 8.2 provides a top-level block diagram of the TMUX6121, TMUX6122, and TMUX6123. The devices are 2-channel, single-ended, analog switches. Each channel is turned on or turned off based on the state of the address lines and enable pin.
