FEATURES
• Two independent amplifiers with open-loop gain of 90 dB (typical)
• Internal DC feedback via 140 kΩ resistor from output to feedback point
• AC characteristics that can be determined externally by an RC network
• Electronic on/off switching with transient suppression for switch on
• Head input at DC ground that eliminates the input coupling capacitor
• Minimum external component requirement
• Stability down to a gain of 30 dB
• Low input noise
• Low distortion
• DC input current <2 µA.
GENERAL DESCRIPTION
