These highly integrated, programmablegain differential amplifiers are engineered for precise low frequency, high dynamic range measurements. Based on Cirrus Logic’s patented Multipath™ amplifier architecture, these powerful amplifiers provide unrivaled noise and drift performance. Low-power consumption combined with -121 dB THD performance makes them ideal for today’s seismic applications. Chopper stabilized and designed for use with geophone sensors, the CS3301A delivers impressive low noise, low drift performance down to 0.1 Hz. The high input impedance of the CS3302A makes it well suited for use with hydrophone sensors, while still delivering outstanding noise and drift performance. With an extensive feature set and available in a 24-pin SSOP package, these amplifiers provide an outstanding price/performance combination for seismic applications. Low Noise & Low Power. New Seismic Amplifiers Deliver Outstanding Price/ Performance Combination. 7.9 mm CS3301A/CS3302A 24-pin SSOP dimensions 7.4 mm CS3301A/02A www.cirrus.com
