ADS7808U/1KG4

Analog To Digital Converters (ADC) Overview

The ADS7808U/1KG4 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 100 kSPS and features a serial CMOS interface. The device supports both external and internal reference modes and accepts single-ended inputs. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 73 dB and a power consumption of 81.5 mW. The component is housed in a SOIC-20 package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 12-bit SAR ADC core with a serial output interface for simplified system connectivity.
• Supports flexible reference configurations allowing selection between external precision references or the internal bandgap source.
• Delivers consistent linearity performance with specified differential and integral nonlinearity values across the operating temperature range.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise analog signal digitization
• Data acquisition modules for sensor interfacing
• Portable instrumentation powered by single-supply architectures

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm lead-free compliance status and exact ordering details. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 100 kSPS throughput are sufficient for the application. Consider the serial interface complexity versus parallel alternatives like the ADS7804 if pin count is constrained. Evaluate the need for internal versus external voltage references based on required accuracy levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS780x family of low-power, high-speed ADCs from Texas Instruments. It shares architectural similarities with other members such as the ADS7804 and ADS7809 but differs in resolution and interface type. The U/1K designation indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same series include the ADS7808UB for tube packaging. For higher resolution needs, the ADS7809 offers 16-bit performance. For parallel interfaces, the ADS7804 provides comparable speed with different connectivity.
