Sine Function Generators
Similar functions can be formulated to approximate a SINE
function converter as shown in Figure 22. With a linearly
changing (0 to 5V) input the output will follow 0
o
to 90
o
of a
sine function (0 to 5V) output. This configuration is theoreti-
cally capable of
±
2.1% maximum error to full scale.
By adding a second HA-2556 to the circuit an improved fit
may be achieved with a theoretical maximum error of 0.5%
as shown in Figure 23. Figure 23 has the added benefit that
it will work for positive and negative input signals. This
makes a convenient triangle (
±
5V input) to sine wave (
±
5V
output) converter.
