TC534CPJ Datasheet PDF - TelCom Semiconductor, Inc

GENERAL DESCRIPTION
The TC530/534 are serial analog data acquisition subsystems ideal for high precision measurements (up to 17 bits plus sign). The TC530 consists of a dual slope integrating A/D converter, negative power supply generator and 3 wire serial interface port. The TC534 is identical to the TC530, but adds a four channel differential input multiplexer. Key A/D converter operating parameters (Auto Zero and Integration time) are programmable, allowing the user to trade-off conversion time for resolution.
