ADS7806U/1KE4

Analog To Digital Converters (ADC) Overview

The ADS7806U/1KE4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a single 5V supply and supports sampling rates up to 40 kSPS. The device features a serial interface compatible with SPI, Microwire, and QSPI standards. Key electrical specifications include a differential nonlinearity (DNL) of -2/3 LSB and an integral nonlinearity (INL) of +/- 3 LSB. It functions within an industrial temperature range of -40°C to +85°C and consumes approximately 28 mW of power.

Analog To Digital Converters (ADC) Feature Summary

• Supports flexible digital interfaces including SPI, Microwire, and QSPI for system integration
• Operates from a single 5V power supply to simplify board design
• Provides high accuracy with specified DNL and INL performance metrics

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise signal acquisition
• Data acquisition modules for sensor interfacing
• Battery-powered instrumentation utilizing low-power SAR architecture

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1KE4' against official Texas Instruments documentation to confirm packaging details and reel specifications. Ensure compatibility with standard SOIC-28 footprints during PCB layout. Confirm that the component meets RoHS compliance requirements for your target market before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 40 kSPS is sufficient for the application. Consider the ADS7806U/1KE4 over higher-resolution models if power consumption must remain below 30 mW. Verify that the single-ended input configuration aligns with the source signal characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS780x family of low-power, 12-bit ADCs. It shares architectural similarities with the ADS7807 and ADS7809 but offers lower resolution than the 16-bit variants. The U package denotes a plastic small-outline integrated circuit (SOIC) suitable for surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other members of the ADS780x series such as the ADS7807 or ADS7809, provided pin compatibility and resolution requirements are met. Verify interface timing differences when migrating between different bit-depth versions in the same family.
