ICL7135CN Datasheet

Analog to Digital Converters - ADC


The ICL7135CN and TLC7135C converters are manufactured with Texas Instruments highly efficient CMOS technology. These 4 1/2-digit, dual-slope-integrating, analog-to-digital converters (ADCs) are designed to provide interfaces to both a microprocessor and a visual display. The digit-drive outputs D1 through D4 and multiplexed binary-coded-decimal outputs B1, B2, B4, and B8 provide an interface for LED or LCD decoder/drivers as well as microprocessors. ICL7135CN Features • Zero Reading for 0-V Input• Precision Null Detection With True Polarity at Zero• 1-pA Typical Input Current• True Differential Input• Multiplexed Binary-Coded-Decimal (BCD) Output• Low Rollover Error: ±1 Count Max• Control Signals Allow Interfacing With UARTs or Microprocessors• Autoranging Capability With Over-and Under-Range Signals• TTL-Compatible Outputs
