Uses Siliconix LD111 IC analog processor section of digital voltmeterIC pair to combine desirable features of digital voltmeter with signal-averaging advantages of ordinary meter. Input range covered is 10 mV to 3 V, with resistive divider being required for larger input voltage. Differential inputs each have 1-gigohm input impedance. Circuit requires only two 9-V batteries. Article describes operation in detail.-B. Harvey, Digital Voltmeter IC Drives Analog Meter, EDN Magazine, June 20, 1977, p 113.
