ADS7807U/1KE4

Analog To Digital Converters (ADC) Overview

The ADS7807U/1KE4 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 configuration and offers flexible interface options including parallel and SPI modes. Key performance metrics include an SNR of 88 dB, DNL of -2/3 LSB, and INL of +/- 3 LSB. It functions within an ambient temperature range of -40°C to +85°C and is housed in a SOIC-28 package.

Analog To Digital Converters (ADC) Feature Summary

• Configurable input ranges via external resistors for flexible signal interfacing
• Dual interface support allowing selection between parallel and serial communication protocols
• Integrated internal reference option alongside external reference capability

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Medical instrumentation utilizing single-supply operation
• Data logging applications with moderate sampling rate requirements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix /1KE4 against official Texas Instruments documentation to confirm packaging quantity and reel specifications. Ensure compatibility with RoHS directives as indicated in current datasheets. Confirm that the SOIC-28 package matches the target PCB footprint design constraints before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is required with low power consumption under 35 mW. It is suitable for designs needing either parallel or serial connectivity without additional logic. Consider the single-ended input limitation and verify that the 40 kSPS speed meets system bandwidth needs. Check if the internal reference accuracy suffices or if an external precision reference is necessary for higher accuracy.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7807 family of CMOS sampling ADCs designed for general-purpose data acquisition. It complements other devices like the ADS7809 which offers higher sampling speeds but different interface characteristics. The U variant denotes the SOIC-28 surface-mount package, distinguishing it from ceramic or plastic DIP options available in the broader series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include ADS7807 variants with different package codes such as ADS7807U or ADS7807N. For higher speed requirements, consider the ADS7809. Verify pinout compatibility and electrical specifications against the new component's datasheet before implementation.
