Sine Function Generators
Similar functions can be formulated to approximate a SINE
function converter as shown in Figure 22. With a linearly
changing (0V to 5V) input the output will follow 0 degrees to 90
degrees of a sine function (0V to 5V) output. This configuration
is theoretically 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.
