SCDS384A September 2018 – December 2018 TMUX6119
PRODUCTION DATA.
One application to take advantage of TMUX6119’s precision performance is the implementation of the chopper amplifier. The chopper amplifier was developed in the 1950s to achieve ultra-low offset voltage and low offset voltage drift over time and temperature. It also drastically reduces low frequency 1/f (flicker) noise. These attributes make the chopper amplifier ideal for small signal conditioning. Figure 34 illustrates a classic example of a simple chopper amplifier implemented with two TMUX6119 SPDT switches.
