CS3302A  
High-Z, Programmable Gain, Differential Amplifier  
Features & Description  
Description  
The CS3302A is a high input-impedance, differential in-  
put, differential output amplifier with programmable  
gain, optimized for amplifying signals from high-imped-  
ance 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 ex-  
ternal inputs, INA and INB, simplify system design as  
inputs from a sensor and test DAC. An internal 800Ω  
termination can also be selected for noise tests.  
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, 800termination  
• Rough / fine charge outputs for CS5371A / 72A / 73A  
• Max signal amplitude: 5 V differential  
pp  
• Ultra-low input bias: < 1 pA  
z Excellent Noise Performance  
Amplifier input impedance is very high, requiring less  
than 1 pA of input current. Noise performance is very  
good at 1 µVp-p between 0.1 Hz and 10 Hz, and a noise  
density of 8.5 nV/ Hz over the 200 Hz to 2 kHz band-  
width. 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.  
• 1 µV between 0.1 Hz and 10 Hz  
p-p  
• 8.5 nV/ Hz from 200 Hz to 2 kHz  
z Low Total Harmonic Distortion  
• -118 dB THD typical (0.000126%)  
• -112 dB THD maximum (0.000251%)  
z Low Power Consumption  
• Normal operation: 5 mA  
• Power down: 10 µA
