CS3302 High-Z, Programmable Gain, Differential Amplifier Features & Description z Signal Bandwidth DC to 2 kHz z Selectable Gain x1, x2, x4, x8, x16, x32, x64 z Differential Inputs, Differential Outputs • Multiplexed inputs INA, INB, termination • Rough / fine charge outputs for CS5371/72 • Max signal amplitude 5 Vpp differential • Ultra-low input bias < 1 pA z Excellent Noise Performance • 1 µVp-p between Hz and 10 Hz • nV/ from 200 Hz to 2 kHz z Low Total Harmonic Distortion • -118 dB THD typical • -112 dB THD maximum z Low Power Consumption • Normal / LPWR / PWDN 5 mA, mA, 10 µA z Single or Dual Power Supply Configurations • VA+ = +5 V VA- = 0 V VD = V to +5 V • VA+ = V VA- = V VD = V The CS3302 is a high-input-impedance, differential input, differential output amplifier with programmable gain, optimized for amplifying signals from high-impedance sensors such as hydrophones. 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 termination can also be selected for noise tests. Amplifier input impedance is very high, requiring less than 1 pA of input current. Noise performance is very good at 1 µVp-p between Hz and 10 Hz, and a noise density of nV/ over the 200 Hz to 2 kHz bandwidth. Distortion performance is also extremely good, typically -118 dB THD. Low input current, low noise, and low total harmonic distortion make this amplifier ideal for high-impedance differential sensors requiring maximum dynamic range.
