Product description:
The core of the special instrument amplifier, rail-to-rail output, high input impedance, high co-mode inhibitory ratio, low maladjustment and drift, low noise, and high closed loop gain stability, precision measurement/amplification are selected.
Module features:
- high-end special instrument amplifier ad 623 core, high precision, good linear.
- single power supply, support 3-5.5v power supply, easy to use!
- integration of negative voltage generation module, dual power supply operation, easy response to negative signal/ac signal.
- power input lc filter, pure and stable, to guarantee the stability of signal amplification.
- built-in negative voltage generation module, only single power supply can operate double power supply, simplify system design.
- rail-to-rail output, maximum output swing up to+- vcc, far exceeding core products such as lm358/ad620 (vcc-1.5v only)
- 2-1000-fold magnification adjustable, suitable for different applications, imported american rounds potentiometers, uniform resistance change, stable resistance value, more than 10 times higher than domestic potentiometer(Low-quality potentiometers are often loose, open, beat, causing resistance to be large and small, open, etc.)。
- the module is simple, expandable, detailed and convenient for secondary development.
Main parameters:
Amplifier type: special instrument amplifier ad623 core
Input range: 0.5 vcc (i.e., between s+/ s - voltages less than half the voltage of the power supply).)
Output range:+- vcc (rail-to-rail)
Magnification multiples: 2-1000 times adjustable.
Power consumption: 150ua (typical) 650ua (maximum)
Power supply: 3-5.5v
Gain accuracy: 0.35% (g > 2) 0.10% (g = 2)
Input mismatch voltage: 100-200uv
Input dislocation drift: 1uv/°C
Comode inhibition ratio: 90db
Gain bandwidth: 800 khz.
Pcb size: 40x23mm with m3 installlation holes 4pcs
It is recommended that smaller magnification times (e.g. 50/100 times) be used to test the baby and then move to the required multiples.Adjust a++ knobs clockwise to increase magnification (up to 1000 times), and when adjusting to the maximum, you can hear the potentiometer make a slight click, which means that it has been adjusted to the end.Resistance can also be used to fix magnification times, so that magnification values are more stable.
Points to note
- some people call the ref zero-tone tube foot, which is ok, but the ad 623 core is highly accurate, grounding the ref directly, and the output is very close to 0, without actually having to be adjusted.It is recommended that ref foot voltage be adjusted only when a flat voltage is required
- our shop uses imported american rounds potentiometers, which are uniformly regulated, stable, reliable, 10 times higher than domestic potentiometers and comparable to non-domestic potentiometers.
