ADS7808UBG4

Analog To Digital Converters (ADC) Overview

The ADS7808UBG4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a single-ended input and features a serial interface for data output. The device supports sampling rates up to 100 kS/s with a conversion time of 10 microseconds. 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, differential nonlinearity of +/- 0.45 LSB, and integral nonlinearity of +/- 0.45 LSB. Power consumption is specified at 81.5 mW, with a maximum power dissipation of 100 mW. The component is housed in a 20-pin SOIC package and operates across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix and manufacturer documentation before procurement, as the ADS7808UBG4 may be listed as obsolete or discontinued in current catalogs. Confirm availability through authorized distributors or surplus channels, ensuring that the component meets RoHS compliance standards and matches the required SOIC-20 package specifications for your application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 100 kS/s sampling rate are sufficient for the target application. Consider the single-ended input configuration and 5V supply requirement. Evaluate the trade-off between the 100 mW power dissipation and the need for serial connectivity. Ensure the system can accommodate the +/- 0.45 LSB linearity specifications for accurate measurement requirements.

Analog To Digital Converters (ADC) Part Context

The ADS7808 belongs to the ADS7808 series of 12-bit CMOS sampling ADCs from Texas Instruments. This series is designed for applications requiring moderate speed and resolution. The UBG4 suffix indicates a specific tape-and-reel or tube packaging variant compliant with lead-free standards, distinct from earlier versions like the ADS7808U.
