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
Figure 1 shows the circuit diagram for a noninverting amplifier. The voltage gain of this amplifier is
given by the following formula.

3. High Input Impedance DC Differential Amplifier
The circuit shown in figure 3 is a high input impedance DC differential amplifier. This circuit's
common-mode rejection ratio (CMR) depends on the matching between the R

2
and R

ratios. This amplifier's output is given by the following formula.

4. Voltage Controlled Oscillator
Figure 4 shows an oscillator circuit in which the amplifier A
1
is an integrator, the amplifier A
2
is a
comparator, and transistor Q
1
operates as a switch that controls the oscillator frequency. If the output
Vout1 is at the low level, this will cut off transistor Q1 and cause the A
1
inverting input to go to a higher
potential than the noninverting input. Therefore, A
1
will integrate this negative input state and its output
level will decrease. When the A
1
integrator output becomes lower than the A
2
comparator noninverting
input level (V
CC
/2) the comparator output goes high. This turns on transistor Q
1
causing the integrator to
integrate a positive input state and for its output to increase. This operation generates a square wave on
Vout1 and a triangular wave on Vout2.
