A-622L
Low noise amplifier for load cells
The A-622L is a load cell amplifier that incorporates a power supply for driving load cells and can be directly connected to a 350Ω load cell. It uses a low-noise measurement amplifier IC (Analog Devices AD8221AR) and operates on a single +5V power supply with a required current of 25mA. It is equipped with trimmers for sensitivity adjustment and offset adjustment, making it easy to calibrate. Rated output: 2V, sensitivity adjustment range: 0.5 to 2.2mV, offset adjustment range: +2.5V ±0.5V. The response frequency is kept low, resulting in minimal residual output noise.
