Features:
1. High voltage working range
Power supply voltage: usually ± 15V~± 110V (single power supply 24V~220V)
Far beyond the general operational amplifier (usually ± 15V/30V upper limit), it can directly process high-voltage signals, eliminating the need for voltage division/reduction.
2. Ultra high precision (DC parameters)
Input offset voltage (Vos): ≤ 50 μ V (typical 10-30 μ V)
Offset voltage drift (TCVos): ≤ 1-2 μ V/℃, with minimal temperature drift
Open loop gain (Aol): 130~170dB (over one million times), amplifying without distortion
Common mode rejection ratio (CMRR): 110-160dB, super strong suppression of common mode interference
3. Extremely low noise (AC parameters)
Voltage noise density: 3-10 nV/√ Hz @ 1kHz
Low frequency noise (0.1~10Hz): ≤ 0.2~0.5 μ Vp-p
Suitable for amplifying nV~μ V level weak signals (sensors, bioelectricity, precision detection).
4. Excellent dynamic performance
Gain bandwidth product (GBW): 5~82MHz
Swing ratio (SR): 10~74 V/μ s, high-speed signal distortion free
Stable unit gain, sufficient phase margin, and reliable closed-loop application.
5. High reliability
Wide temperature range: -40 ℃~+125 ℃
Built in overvoltage/overcurrent/overheat protection
High Power Supply Rejection Ratio (PSRR), resistant to power ripple
