ADS7807UBG4

Analog To Digital Converters (ADC) Overview

The ADS7807UBG4 is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single 5V supply with power consumption of 28 mW and supports sampling rates up to 40 kSPS. The device features a single-ended input architecture and offers flexible interface options including parallel and SPI modes. Key performance metrics include an SNR of 88 dB, DNL of -1/1.5 LSB, and INL of +/- 1.5 LSB. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Supports both parallel and serial SPI digital interfaces for versatile system integration
• Configurable input ranges via external resistors or internal reference selection
• Low power consumption suitable for battery-operated applications

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Medical instrumentation such as patient monitoring devices
• Precision measurement equipment and test instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to the manufacturer's current documentation. Confirm the package type matches the design requirements, as the base model ADS7807 may appear in various packages like SOIC-28. Ensure the supplier provides valid traceability documents for moisture sensitivity level handling during procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 40 kSPS speed are required with low power constraints. Compare against the ADS7808 if higher speed but lower resolution is acceptable. Verify that the single-ended input configuration meets the signal source requirements, as differential inputs are not supported in this specific part number.

Analog To Digital Converters (ADC) Part Context

The ADS7807 belongs to the ADS78xx family of CMOS sampling ADCs from Texas Instruments. This series is designed for general-purpose data acquisition tasks. The UBG4 variant specifically denotes the SOIC-28 package with green (RoHS compliant and no Sb/Br) compound material. It serves as a bridge between high-speed converters and precision sigma-delta ADCs in terms of performance and power.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADS7807IBDW. For upgraded performance, consider the ADS8507IBDW which offers similar specifications. Always verify electrical compatibility and software driver support before substituting.
