ADS7808UB/1K

Analog To Digital Converters (ADC) Overview

The ADS7808UB/1K 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 kS/s and supports single-ended input signals. The device utilizes a serial interface for data communication and 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 signal-to-noise and distortion ratio of 73 dB. Differential nonlinearity and integral nonlinearity are specified at +/- 0.45 LSB. The component is housed in a SOIC-20 package, consumes 81.5 mW of power, and operates across a temperature range of -40°C to +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 both external and internal reference configurations to accommodate varying design requirements.
• Delivers precise conversion accuracy with low differential and integral nonlinearity specifications.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring accurate analog signal digitization
• Data acquisition modules for sensor interfacing
• Portable instrumentation powered by standard 5V logic supplies

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix /1K confirms the reel packaging quantity of 1000 units as indicated in distributor records. Ensure the SOIC-28 or SOIC-20 package designation aligns with your PCB footprint requirements, noting that datasheet variations may exist between source listings. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application's dynamic range needs. The 100 kS/s sampling rate suits moderate-speed data acquisition tasks rather than high-frequency waveform capture. Consider the serial interface requirement against available microcontroller SPI or proprietary serial ports. The 5V supply operation simplifies power design compared to lower-voltage alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7808 series of CMOS sampling analog-to-digital converters. It shares architectural similarities with other devices in the family but differs in resolution and interface type. The ADS7809 offers higher 16-bit resolution, while the ADS7804 provides parallel interface options. This specific model targets applications balancing cost, pin count, and moderate precision requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same package and specification profile are not explicitly confirmed in public documentation. The ADS7808UB without the /1K suffix represents the same device in tube packaging. Cross-referencing with ADS7804 or ADS7809 requires evaluating interface compatibility and resolution differences.
