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.

The TC530/534 timebase can be derived from an external crystal of 2MHz (max), or from an external frequency source. The TC530/534 requires a single 5V power supply and features a – 5V, 10mA output which can be used to supply negative bias to other components in the system.
