ADS7800KUG4

Analog To Digital Converters (ADC) Overview

The ADS7800KUG4 is a 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a parallel interface and single-ended input type. The device operates on a single 5V supply, with both analog and digital power voltages ranging from 4.75 V to 5.25 V. It achieves a sampling rate of 333 kS/s with a typical sampling time of 3 µs. Key performance metrics include a signal-to-noise ratio (SNR) of 73 dB, differential nonlinearity (DNL) of ±0.75 LSB, and integral nonlinearity (INL) of ±0.5 LSB. The component is housed in a 24-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm RoHS compliance status and pinout compatibility. Ensure the ordering information matches the exact package variant required for your PCB layout. Cross-reference the part number with official Texas Instruments documentation to validate availability and any potential lifecycle changes before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 333 kSps throughput are required with a parallel interface. It is suitable for applications where an internal reference is preferred over external components. Consider the 24-pin SOIC package constraints and the 5V supply requirement during system design. Compare DNL and INL specifications against application tolerance levels to ensure adequate accuracy.

Analog To Digital Converters (ADC) Part Context

The ADS7800KUG4 belongs to the ADS7800 series of monolithic CMOS sampling analog-to-digital converters. This family is designed for general-purpose data acquisition tasks. The KUG4 designation indicates a specific package and temperature grade within the broader ADS7800 product line, sharing core architectural features with other variants in the series while differing in packaging and environmental ratings.

Analog To Digital Converters (ADC) Replacement Considerations

Check for ADS7800KU or ADS7800KUE4 as potential functional equivalents within the same series. Verify pin compatibility and electrical parameter alignment before substitution. Consult Texas Instruments documentation for updated replacement recommendations if the current part is discontinued.
