The outputs of the data register are updated one clock cycle before the rising edge of EOC. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Resistor Ladder and Switch Tree. It is also the comparator drift which has the greatest influence on the repeatability of the device.

The outputs of the data register are updated one clock cycle before the rising edge of EOC. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Resistor Ladder and Switch Tree. It is also the comparator drift which has the greatest influence on the repeatability of the device. National Semiconductor Japan Adccnc.
This technique limits the drift component of the amplifier since the drift is a DC component which is not passed by the AC am- plifier. The device contains an 8-channel single-ended analog signal multiplexer.
The successive approximation register SAR performs 8 it- erations to approximate the input voltage. Measured at Ref. Page 12 Ratiometric transducers 3. End-of-conversion will go low between 0 and 8 clock pulses after the rising edge of start conversion.
The ADC needs less than a milliamp of supply current so developing the supply from the reference is readily ac- complished. The voltages at the top, center and bottom of the ladder must be controlled to maintain proper operation. The converter is designed to give fast, accurate, and repeatable conversions over a wide range of temperatures.
This means a sys. Minimum Start Pulse Width. Page 1 of adcccn datasheet Puoi verificare le tue adcccn datasheet visitando: The top and bottom ladder voltages cannot exceed V. A zener diode exists, internally, from Dwtasheet. For channel mul- tiplexer. The device eliminates the need for external zero and full-scale adjustments. The center of the ladder volt. This signal is then fed through a high gain AC amplifier and has the DC level restored. The output code N for an arbitrary input are the integers within the range: Additionally, the R network does not cause load variations on the ref- erence voltage.
SA Thru Sense A. Comparator input current is a bias current into or out of the chopper datasheett comparator. Temperature Range Note 1. The R ladder network approach. Seuls les dataasheet prenant adcccn charge TLS 1. N-channel switches to P- channel switches. If input filter capacitors are desired for noise reduction and signal conditioning they will tend to average out the dynamic comparator input current.

Minimum Address Set-Up Time. These limitations are automatically satis- fied in ratiometric systems and can be easily met in ground referenced Mouser Electronics heeft TLS 1. Page 8 Typical Performance Characteristics adcc9cn. Life support devices or systems are devices or. Analog Input Voltage Range. The successive approximation register SAR performs 8 it- erations to approximate the input voltage.
