TC534CPL [Microchip]

The TC530/TC534 are serial analog data acquisition subsystems featuring a dual slope integrating A/D converter, negative power supply generator, and 3-wire serial interface. The TC530 adds a four-channel differential input multiplexer. Key parameters (Auto Zero and Integration time) are programmable, allowing trade-off between conversion speed and resolution. They operate from a single 5V supply, include a -5V output pin, and support automatic input polarity and overrange detection. Features include precision up to 17 bits, low operating current (5mA max), and wide analog input range (±4.2V max).
