ML145041 - LANSDALE Semiconductor

ML145041 (ML145040 / ML145041) 8-Bit A/D Converters

DIGITAL INPUTS AND OUTPUTS CS (Pin 15) Active–low chip select input. CS provides three–state control of Dout. CS at a high logic level forces Dout to a high–impedance state. IN addition, the device recognizes the falling edge of CS as a serial interface reset to provide synchronization between the MPU and the A/D converter’s serial data stream. To prevent .

  –chip test voltage of (Vref + VAG)/2, and produces an output of $80 if the converter is functioning properly. However, a ± 1 LSB deviation from $80 occurs in the presence of sufficient system noise (external to the chip) on VDD, VSS, Vref or VAG. POWER AND REFERENCE PINS VSS and VDD (Pins 10 and 20) Device supply pins. VSS is normally connected to digital ground; VDD is connected to a positive digital supply voltage. VDD .
