1 / 24 page OBSOLETE ADC08131, ADC08134, ADC08138 www.ti.com SNAS066D – JUNE 1999 – REVISED APRIL 2013 ADC08131/ADC08134/ADC08138 8-Bit High-Speed Serial I/O A/D Converters with Multiplexer Options, Voltage Reference, and Track/Hold Function Check for Samples: ADC08131, ADC08134, ADC08138 1 FEATURES DESCRIPTION The ADC08131/ADC08134/ADC08138 are 8-bit 23 • Serial Digital Data Link Requires Few I/O Pins successive approximation A/D converters with serial • Analog Input Track/Hold Function I/O and configurable input multiplexers with up to 8 • 4- or 8-Channel Input Multiplexer Options with channels. The serial I/O is configured to comply with Address Logic the MICROWIRE serial data exchange standard for easy interface to the COPS™ family of controllers, • On-Chip 2.5V Band-Gap Reference (±2% Over and can easily interface with standard shift registers Temperature Ensured) or microprocessors. • No Zero or Full Scale Adjustment Required All three devices provide a 2.5V band-gap derived • TTL/CMOS Input/Output Compatible reference with ensured performance over • 0V to 5V Analog Input Range with Single 5V temperature. Power Supply A track/hold function allows the analog voltage at the positive input to vary during the actual A/D APPLICATIONS conversion. • Digitizing Automotive Sensors The analog inputs can be configured to operate in • Process Control/Monitoring various combinations of single-ended, differential, or pseudo-differential modes. In addition, input voltage • Remote Sensing in Noisy Environments spans as small as 1V can be accommodated. • Embedded Diagnostics KEY SPECIFICATIONS • Resolution: 8 Bits • Conversion Time (fC = 1 MHz): 8 µs (Max) • Power Dissipation: 20 mW (Max) • Single Supply: 5 VDC (±5%) • Total Unadjusted Error: ±½ LSB and ±1 LSB • Linearity Error (VREF = 2.5V): ±½ LSB • No Missing Codes (Over Temperature) • On-Board Reference: +2.5V ±1.5% (Max) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 COPS is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
