ADS7804UG4

Analog To Digital Converters (ADC) Overview

The ADS7804UG4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a single 5V supply and features a parallel interface for data output. The device supports sampling rates up to 100 kS/s and accepts single-ended analog inputs within a 0V to 5V range. Key performance metrics include a signal-to-noise ratio of 73 dB and an integral nonlinearity of ±1 LSB. It is housed in a 28-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per Texas Instruments documentation. Confirm the package type is SOIC-28 and check for moisture sensitivity levels if storage conditions are critical. Ensure the operating voltage matches the required 5V single-supply architecture before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution is sufficient for the application, offering a balance between cost and performance compared to higher-resolution models. Consider the parallel interface requirement; if serial communication is preferred, alternative SPI-based ADCs from the same family may be more suitable. Evaluate the 100 kS/s speed against the actual signal bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

The ADS7804 belongs to the ADS780x series of high-speed, low-power CMOS analog-to-digital converters. This series is designed for applications requiring moderate resolution and fast conversion times. The UG4 designation typically refers to the specific package variant and environmental compliance attributes defined by the manufacturer.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the ADS780x family include the ADS7805 (16-bit) or ADS7809 (12-bit). For similar specifications, consider the ADS7804E or ADS7804U depending on the required package and temperature grade. Verify interface compatibility when substituting.
