CS5374 www.DataSheet4U.com Dual High-performance Amplifier & ΔΣ Modulator
Features
High Input Impedance Differential Amplifier
• Ultra-low input bias: < 1 pA • Max signal amplitude: 5 Vpp differential
Description
The CS5374 combines two marine seismic analog measurement channels into one 7 mm x 7 mm QFN package. Each measurement channel consists of a high input impedance programmable gain differential amplifier that buffers analog signals into a high-performance, fourth-order ΔΣ modulator. The low-noise ΔΣ modulator converts the analog signal into a one-bit serial bit stream suitable for the CS5376A digital filter. Each amplifier has two sets of external inputs, INA and INB, to simplify system design as inputs from a hydrophone sensor or the CS4373A test DAC.
