Specifications

• Input voltage range : DC 3~12V

• Amplification : adjustable 1.5~1000 times, adjustable zero

• Signal input voltage range : 100µV~300mV

• Signal output range : ± (Vin-2V)

• Negative voltage output : > -Vin, for the output resistance of negative voltage chip, the actual output is greater than -Vin, the greater the load power, the greater the negative voltage drop.

• Offset voltage : 50µV
