Zero Drift Amplifiers (Low
Voltage Precision Op Amps)
Chopper-stabilized amplifiers (Zero Drift Amplifiers) offer
one of the best solutions, for the lowest offset voltage and
drift. These amplifiers achieve high DC precision through
a continuously running calibration mechanism that is
implemented on-chip.
Features and Benefits
• Low Drift / Reduced Offset Voltage Over Temperature
• Low Drift /Reduced Offset Voltage Over Time [Figure 2]
• Low Offset Voltage / Reduced Offset Voltage (typically <1µV)
• Low Offset Voltage Over the Common Mode Range and
• Eliminates or No 1/f Noise [Figure 5]
• Very High Open Loop Gain
• Precision Signal Amplifications
Low Voltage Ultra Precision
(typically < 0.5nV/ºC) [Figure 1]
