HA17902 Application Examples
The HA17902 is a quad operational amplifier, and consists of four operational amplifier circuits and one
bias current circuit. It features single-voltage power supply operation, internal phase compensation, a wide
zero-cross bandwidth, a low input bias current, and a high open-loop gain. Thus the HA17902 can be used
in a wide range of applications. This section describes several applications using the HA17902.
1. Noninverting Amplifier
2. Summing Amplifier
Figure 1 shows the circuit diagram for a noninverting amplifier. The voltage gain of this amplifier is
given by the following formula.
Since the circuit shown in figure 2 applies +V
the inverting input, the total output will be Vout = V
