A-M Systems
Differential AC Amplifier Model 1700
Each amplifier contains a high-gain, low-noise differential stage followed by low-frequency, high frequency, and notch filters. A connection is also provided for a stimulator input so that recording or stimulating through an electrode is possible.
- Gain selections include x100, x1,000, and x10,000
- Low noise (1.0 µV peak to peak)
- High common-mode rejection (> 70 dB at 60 Hz)
- High line frequency rejection with notch filter (>110 dB at 60 Hz)
- High input impedance (100,000 MΩ)
- Low input bias current (3 pA typical; 20 pA maximum)
- Driven cable shield for reduced capacitance
- Adjustable low and high frequency filters
- Notch filter for 50 or 60 Hz interference
