Product Summary
The CS3301A-ISZ is a low-noise differential input, differential output amplifier with programmable gain, optimized for amplifying signals from low-impedance sensors such as geophones. The gain settings are binary weighted (x1, x2, x4, x8, x16, x32, x64) and are selected using simple pin settings. Two sets of external inputs, INA and INB, simplify system design as inputs from a sensor and test DAC. An internal 800 Ω termination can also be selected for noise tests. Amplifier noise performance of the CS3301A-ISZ is outstanding with a noise density of 8.5 over the 0.1 Hz to 2 kHz bandwidth. Distortion performance is also extremely good, typically -121 dB THD at x1 gain. Flat noise down to 0.1 Hz and low total harmonic distortion make this amplifier ideal for low-frequency, low-amplitude, differential signals requiring maximum dynamic range.
