Scale-factor adjustable to provide up to ×10 gain

Low noise design: 90 mV rms, 10 Hz to 10 kHz

Low cost, monolithic construction

Excellent long-term stability

APPLICATIONS

High quality analog signal processing

Differential ratio and percentage computations

Algebraic and trigonometric function synthesis

Accurate voltage controlled oscillators and filters
