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.

Figure 1 Noninverting Amplifier 2. Summing Amplifier Since the circuit shown in figure 2 applies +V1 and +V2 to the noninverting input and +V3 and +V4 to the inverting input, the total output will be Vout = V1 + V2 - V3 - V4.

HA17902 Series 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 R1/R2 and R4/R3 resistance ratios. This amplifier's output is given by the following formula.
Vout = 1 +
R4 R3
(V2 - V1)
R2 R1 100k V1 V2 100k - + R3 100k - +
R4 100k Vout
Figure 3 High Input Impedance DC Differential Amplifier 4. Voltage Controlled Oscillator Figure 4 shows an oscillator circuit in which the amplifier A1 is an integrator, the amplifier A2 is a comparator, and transistor Q1 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 A1 inverting input to go to a higher potential than the noninverting input. Therefore, A1 will integrate this negative input state and its output level will decrease. When the A1 integrator output becomes lower than the A2 comparator noninverting input level (VCC/2) the comparator output goes high. This turns on transistor Q1 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.
