s s s s s s s s s s Precision (up to 17 Bits) A/D Converter 3 Wire Serial Port Flexible: User Can Trade-Off Conversion Speed Against Resolution Single Supply Operation –5V Output Pin 4 Input, Differential Analog MUX (TC534) Automatic Input Polarity and Overrange Detection Low Operating Current ............................ 5mA Max Wide Analog Input Range ...................... ±4.2V Max Cost Effective 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. Key A/D converter operating parameters (Auto Zero and Integration time) are programmable, allowing the user to trade-off conversion time for resolution. Data conversion is initiated when the RESET input is brought low. After conversion, data is loaded into the output shift register and EOC is asserted indicating new data is available.
