The serial I/O is configured to comply with the NSC MICROWIRE serial data exchange standard for easy interface to the COPS family of controllers, and can easily interface with standard shift registers or microprocessors. The ADC08034 and ADC08038 provide a 2.6V bandgap derived reference. For devices offering specific voltage reference performance over temperature see ADC08131, ADC08134 and ADC08138. A track/hold function allows th e analog voltage at the positive input to vary during the actual A/D conversion. The analog inputs can be configured to operate in various combinations of single-ended, differential, or pseudo-differential modes. In addition, input voltage spans as small as 1V can be accommodated. 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.

SOIC Package: Storage Temperature Vapor Phase (60 sec.) Infrared (15 sec.) 6.5V −0.3V to VCC + 0.3V ±5 mA ±20 mA 800 mW 1500V 235°C 215°C 220°C −65°C to +150°C (1) All voltages are measured with respect to AGND = DGND = 0 VDC, unless otherwise specified. (2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (4) When the input voltage VIN at any pin exceeds the power supplies (VIN < (AGND or DGND) or VIN > VCC) the current at that pin should be limited to 5 mA. The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four pins. (5) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA and the ambient temperature, TA. The maximum allowable power dissipation at any temperature is PD = (TJMAX − TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For these devices, TJMAX = 125°C. Th.
