2.048MHz Oscillator for 100sps Output Ratio
The oscillator circuit shown in Figure 40 can be used to
drive the F
LTC2420 for applications that do not require a notch at
50Hz or 60Hz. This oscillator is not sensitive to hysteresis
voltage of a Schmitt trigger device as are simpler

relaxation oscillators using the 74HC14 or similar de-
vices. The circuit can be tuned over a 3:1 range with only
one resistor and can be gated. The use of transmission
gates could be used to shift the frequency in order to
provide setable conversion rates.
