As shown in the figure, the basic connection circuit of the signal and power supply of 1NA128/129. The output voltage is based on the standard ground of the output Ref. If there is an 8Ω series resistor, the common mode rejection ratio will drop by about 80dB (G = 1). The selection of gain and RG is shown in the table below. Gain G = 50 kΩ / RG (INA128) or = 149.4 kΩ / RG (INA129). 50kΩ (or 49.4kΩ) is the sum of the feedback resistors of A1 and A2 inside INA128/129.
Optical filter is a kind of optical element that selectively selects the transmission, reflection, cut-off and attenuation of spectral wavelength. According to its function, it can be divided into band pass filter, long wave pass filter, short wave pass filter, two Color filters, neutral density filters (ND Filter), notch filters, cold mirrors, hot mirrors, color filters, etc. Divided into interference filters and color absorption filters. These filters are widely used in industries and product fields such as spectral analysis, biomedicine, machine vision, fluorescence microscopy, and industrial automation. The band-pass filter selectively allows certain spectral wavelengths to pass through and prevents certain spectral wavelengths from passing through in its spectral range; the neutral density filter (ND Filter) reduces the transmittance of the specified spectral wavelength range, thereby Reduce luminous flux, which is conducive to the protection of sensors/electronic components. It has a wide range of applications in the field of laser optics/optoelectronics; cold/hot mirrors can specifically reflect and transmit light with longer wavelengths in the spectral range, and are widely used Applied in the lighting system, it is helpful to remove the heat generated in the lighting system.
