Can MAX187(analog to digital converter) output be used for serial port communication interfacing?
I’m afraid you are wrong! The serial interface on the MAX187 is not the same as the RS232 serial interface on a PC, in fact if you connect it to the RS232 interface you could damage it, because RS232 output voltage can go from +12 to -12V, which is outside the safe range for inputs on the MAX187. The interface on the chip is an SPI interface. It uses 3 lines: -CS: Chip select. Pulling this low initiates a conversion. SCLK: Used to clock data out of the chip. DOUT: Output where the serial data appears. SPI is very common on microcontrollers and peripherals. You can drive the SPI lines from a PC’s parallel port, but it’s a rather clunky way to use it.
