HA17902 series 11 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. = 1 + r2 r1 vout vin + +vin 10k r 1 10k r 2 1m vout figure 1 noninverting amplifier 2. summing amplifier since the circuit shown in figure 2 applies +v 1 and +v 2 to the noninverting input and +v 3 and +v 4 to the inverting input, the total output will be vout = v 1 + v 2 ?v 3 ?v 4 . + r 100k r 100k r 100k r 100k +v 1 +v 2 +v 3 +v 4 r 100 k vout v cc vin(+) vin(?

HA17902 series 12 3. high input impedance dc differential amplifier the circuit shown in figure 3 is a high input impedance dc differential amplifier. this circuit? common-mode rejection ratio (cmr) depends on the matching between the r 1 /r 2 and r 4 /r 3 resistance ratios. this amplifier? output is given by the following formula. vout = 1 + (v 2 ?v 1 ) r 4 r 3 + + r 2 100k w 100k w r 4 r 1 100k w r 3 100k w vout v 1 v 2 figure 3 high input impedance dc differential amplifier 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. + + 100k 10k 51k 51k r 100k v cc v cc a 2 a 1 vout1 vout2 v cc /2 HA17902 HA17902 r/2 50k q 1 +v c c 0.05 m f figure 4 voltage controlled oscillator
