PGA2311 uses a pure resistor network internally, and does not activate the internal amplifier below 0dB. When it exceeds 0dB, it uses an internal amplifier, which is a good front-end indicator. This board is set to -95dB to+31dB, with a step size of 1dB.
Dual AC9V power supply, independent power supply for analog and digital parts to reduce interference. According to the requirements of the PDF, there are Philips 104 decoupling capacitors in both the analog and digital power supply parts of the main chip, which is one of the advantages of this board.
Both digital transistor drivers and relay drivers use dedicated chips.
Strong anti-interference ability, with power-off memory function.
External control switch signal with optocoupler isolation, can be optionally equipped with JP5 power switch board to switch external power supply.
The encoding switch small board can be separated from the display board (connected with double headed wires) or together with the display board (without wiring), which is very flexible; Size: Display board (including coding switch small board) 100mm * 32mm.
