9.3.1 Design Requirements

Small signals from transducers in remote and distributed sensing applications commonly suffer strong 60-Hz interference from AC power lines. The circuit of Figure 36 filters out (notches out) the 60 Hz and provides a system gain of AV = 2 V/V for the sensor signal represented by a 1-kHz sine wave. Similar stages may be cascaded to remove 2nd and 3rd harmonics of 60 Hz. Thanks to the nanopower consumption of the TLV8544, even five such circuits can run for 9.5 years from a small CR2032 lithium cell. These batteries have a nominal voltage of 3 V and an end of life voltage of 2 V. With an operating voltage from 1.7 V to 3.6 V the TLV8544 device can function over this voltage range.
