Optimized for fast channel switching.

On-chip per channel system calibration. Schmitt trigger on logic inputs. The differential reference input features “No-Reference” detect. The ADC also supports per channel system. The digital serial interface can be. The part is specified for operation over the extended industrial. The AD is a high precision, high throughput analog front.

True bit p-p resolution is achievable with a total. catasheet

Other parts in the AD family are the AD and. The part can be configured via a simple digital interface, which. The AD is similar to AD, but its analog front end. The AD analog front end is configurable for four fully. The analog front end features four single-ended input channels. The part has an.

The AD multiplexer output is pinned out externally. Information furnished by Analog Devices is believed to be accurate and reliable. However, no responsibility is assumed by Analog Devices for its use, nor for any. One Technology Way, P. Box datashset, Norwood, MAU. Specifications subject to change without notice.

Power Dissipation Standby Mode See Typi cal Performance Characteristics. Ax7734 system calibration reduces these errors to the order of the noise. Applies after the zero-scale and full-scale calibration.

The negative full-scale error represents the remaining error after removing the offset and gain error. ADC datashee self-calibration reduces this error to? Channel zero-scale system calibration reduces this error to the order of the noise. The output data span corresponds to the specified nominal input voltage range.

The ADC is functional outside the nominal input voltage. Outside the nominal datasheft voltage range, the OVR bit in the channel status register is set and the channel data register. See the register and circuit descriptions for more details. The adjacent channels are not affected by AIN voltage up to?

Pin impedance is from sd7734 pin to the internal node. In normal circuit configuration, the analog input total impedance is typically Part is functional with lower Dataeheet REF. Dynamic current charging the sigma-delta modulator input switching capacitor. Outside the specified calibration range, calibration is possible but the performance may degrade. DV DD of 4. DV DD of 2.

Sample tested during initial release to ensure compliance. See Figure 2 and Figure 3. These numbers are measured with the load circuit of Figure 4 and defined as the time required for the output to cross the V OL or V OH limits.
