ADC0811 Datasheet | National Semiconductor

Description The ADC0811 is an 8-Bit successive approximation A D converter with simultaneous serial I O The serial input controls an analog multiplexer which selects from 11 input channels or an internal half scale test voltage An input sample-and-hold is implemented by a capacitive reference ladder and sampled data parator This allows the input signal to vary during the conversion cycle Separate serial I O and conversion clock inputs are provided to facilitate the interface to various microprocessors Y Y Y Y Y Y Ratiometric or absolute voltage referencing No zero or full-scale adjust required Internally addressable test voltage 0V to 5V input range with single 5V power supply TTL MOS input output patible 0 3 standard width 20-pin dip or 20-pin molded chip carrier Key Specifications Y Y Y Y Y Features Separate asynchronous converter clock and serial data I O clock 11-Channel multiplexer with 4-Bit serial address logic Built-in sample and hold function Resolution Total unadjusted error Single supply Low Power Conversion Time g 8-Bits LSB and g 1LSB 5VDC 15 m W 32 m S Connection Diagrams Dual-In-Line Package Functional Diagram Top View TL H 5587- 1 Molded Chip Carrier (PCC) Package TL H 5587 - 3 Top View TL H 5587- 2 Order Number ADC0811J N V See NS Packages J20A N20A V20A Use Ordering Information C1995 National Semiconductor Corporation TL H 5587 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Notes 1 2) Lead Temp (Soldering 10 seconds) Dual-In-Line Package (plastic) Dual-In-Line Package (ceramic) Molded Chip Carrier Package Vapor Phase (60 seconds) Infrared (15 seconds) ESD Susceptibility (Note 11) 260 C 300 C 215 C 220 C 2000V 2) 4 5 VDC to 6 0 VDC TMINs TAs TMAX 0 Cs TAs70 C b 40 C s TA s 85 C b 40 C s TA s 85 C If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage (VCC) 6 5V Voltage b 0 3V to VCC a 0 3V Inputs and Outputs...
