ADC1034 Datasheet | National Semiconductor

Description The ADC1031 ADC1034 and ADC1038 are 10-bit successive approximation A D converters with serial I O The serial input for the ADC1034 and ADC1038 controls a singleended analog multiplexer that selects one of 4 input channels (ADC1034) or one of 8 input channels (ADC1038) The ADC1034 and ADC1038 serial output data can be configured into a left- or right-justified format An input track hold is implemented by a capacitive reference ladder and sampled-data parator This allows the analog input to vary during the A D conversion cycle Separate serial I O and conversion clock inputs are provided to facilitate the interface to various microprocessors Features Serial I O (MICROWIRETM patible) Separate asynchronous converter clock and serial data I O clock Analog input track hold function Ratiometric or absolute voltage referencing No zero or full scale adjustment required 0V to 5V analog input range with single 5V power supply TTL MOS input output patible No missing codes Resolution 10 bits g 1 LSB (max) Total unadjusted error Single supply 5V g 5% Power dissipation 20 m W (max) Max conversion time (f C e 3 MHz) 13 7 ms (max) Serial data exchange time (f S e 1 MHz) 10 ms (max) Key Specifications Y Y Y Y Y Y Applications Engine control Process control Instrumentation Test equipment TRI-STATE is a registered trademark of National Semiconductor Corporation MICROWIRETM is a trademark of National Semiconductor Corporation Connection Diagrams Dual-In-Line and SO Packages TL H 10556- 4 Top View ADC1031 In NS Package N08E TL H 10556 - 3 Top View ADC1034 In NS Packages J16A M16B or N16E TL H 10556 - 2 Top View ADC1038 In NS Packages J20A M20B or N20A Ordering Information Industrial b40 C s TA s a 85 C ADC1031CIN ADC1034CIN ADC1034CIWM ADC1038CIN ADC1038CIWM Military b55 C s TA s a 125 C ADC1034CMJ ADC1038CMJ Package N08E N16E M16B N20A M20B Package J16A J20A C1995 National Semiconductor Corporation TL H 10556 RRD-B30M75 Printed in U S...
