Features:
1. Ultra low imbalance and drift
Unbalanced voltage VOS: typical<1~10 μ V
Temperature drift dVOS/dT:<0.01~0.05 μ V/° C
Long term drift: approaching zero, 10th grade stability Analog Devices
2. No 1/f flicker noise
Chopping/zeroing technology modulates DC offset and low-frequency noise into AC and filters them out. The low-frequency noise is extremely low and the spectrum is flat. Texas Instruments
3. Ultra high DC precision
High open-loop gain (>120 dB), high common mode rejection ratio (CMRR>120 dB), high power supply rejection ratio (PSRR>120 dB)
4. Other advantages
Track to track input/output (most models)
Wide voltage and wide temperature range (-40 ° C~125 ° C)
Low power consumption, micro package (SOT-23, SC70)
