ADC12441 Datasheet | National Semiconductor

Description The ADC12441 is a CMOS 12-bit plus sign successive approximation analog-to-digital converter whose dynamic specifications (S N THD etc ) are tested and guaranteed On request the ADC12441 goes through a self-calibration cycle that adjusts positive linearity and full-scale errors to less than g LSB each and zero error to less than g 1 LSB The ADC12441 also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion The analog input to the ADC12441 is tracked and held by the internal circuitry and therefore does not require an external sample-and-hold A unipolar analog input voltage range (0V to a 5V) or a bipolar range (b5V to a 5V) can be acmodated with g 5V supplies The 13-bit word on the outputs of the ADC12441 gives a 2’s plement representation of negative numbers The digital inputs and outputs are patible with TTL or CMOS logic levels Applications Y Y Y Y Y Digital signal processing Telemunications Audio High resolution process control Instrumentation Key Specifications Y Y Y Y Y Y Y Y Y Y Resolution Conversion Time Bipolar Signal Noise Total Harmonic Distortion Aperture Time Aperture Jitter Zero Error Positive Full Scale Error g 5V Power Consumption Sampling rate 12 bits plus sign 13 8 ms (max) 76 5 d B (min) b 75 d B (max) 100 ns 100 psrms g 1 LSB (max) g 1 LSB (max) 70 m W (max) 55 k Hz (max) Features Self-calibration provides excellent temperature stability Internal sample-and-hold Bipolar input range with single a 5V reference TRI-STATE is a registered trademark of National Semiconductor Corporation Simplified Block Diagram Connection Diagram Dual-In-Line Package TL H 11017 - 2 Top View Order Number ADC12441CMJ ADC12441CMJ 883 or ADC12441CIJ See NS Package Number J28A TL H 11017 - 1 C1995 National Semiconductor Corporation TL H 11017 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Notes 1 2) Operating Ratings (Notes 1 Temperature Range ADC12441CIJ ADC12441CMJ ADC12441CMJ 883 DVCC...
