ADS7804UB

Analog To Digital Converters (ADC) Overview

The ADS7804UB is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Burr-Brown. It features a serial access interface and is housed in a 20-lead plastic dual small-outline package (PDSO20). The device supports an analog input voltage range up to 2.7 V and achieves a maximum conversion time of 6 µs. It exhibits a maximum linear error of 0.0488% and operates within a temperature range of -40 °C to 85 °C. The output format is binary serial, designed for precision data acquisition applications requiring moderate speed and resolution.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component origin as Burr-Brown or Texas Instruments following the corporate acquisition. Confirm the specific suffix 'UB' corresponds to the required package type and temperature grade against official datasheets. Ensure compliance with relevant regulatory standards if RoHS status is critical for the intended application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and serial interface are required for space-constrained designs. The PDSO20 package offers a compact footprint suitable for dense PCB layouts. Consider the 6 µs conversion speed and 2.7 V input limit to ensure compatibility with the signal source and system timing requirements.

Analog To Digital Converters (ADC) Part Context

The ADS7804 series belongs to Burr-Brown's family of high-performance ADCs. The 'UB' suffix typically denotes the specific plastic dual small-outline package variant. Texas Instruments acquired Burr-Brown, so current documentation may be hosted under the TI brand while retaining the original part numbering conventions.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements should maintain 12-bit resolution and serial interface compatibility. Verify pinout correspondence between the PDSO20 packages. Check that the substitute device meets the same 6 µs conversion time and operating temperature specifications.
