AC/DC Differential Amplifier

Overview:

This AM3000H high gain AC/DC Differential Amplifier is used as a single-ended amplifier. It is designed for low noise recording from excitable tissue and is suitable for EEG, ECG and extracellular recordings. The AM3000H is an ideal unit for teaching and is included in the PTB266 Neurobiology Teaching System. The amplifier also includes a headstage for use with high impedance electrodes. The headstage supports record, stimulate and impedance modes.

Ordering Information:

When ordering the AM3000H AC/DC Differential Amplifier please specify the following.

Mains Power  = 115V/60Hz for 110-115V or 220V/50Hz for 220-240V.
 

Features:

• The input can be amplified from 50 to 10,000 times in both DC and AC modes.
• A high resolution DC Offset adjustment is available up to ±250mV, using Fine and Coarse adjustment controls.
• High Pass, Low Pass, and Notch Filters offer wide frequency selectivity.

Applications:

The AC/DC Differential Amplifier is designed for low-noise recordings from excitable tissue. Specific applications include EEG, EKG and extracellular recordings. For information on experiments suitable for use with the AM3000H Differential Amplifier see our support material in the form of Teaching Experiments available from our Education Experiments section.

The AC/DC Differential Amplifier is NOT approved for use with Human Subjects in either a Clinical or Research Environment.
