ADS7807UB

Analog To Digital Converters (ADC) Overview

The ADS7807UB is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a sampling rate of up to 200 kSPS and operates on a single 5-V supply. The device integrates an internal reference voltage source and supports both parallel and serial SPI-compatible interfaces. Key electrical specifications include a signal-to-noise ratio of 88 dB, differential nonlinearity of -1/1.5 LSB, and integral nonlinearity of +/- 1.5 LSB. Power consumption is rated at 28 mW. 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 manufacturer designation carefully, as the component is produced by Texas Instruments despite historical association with Burr-Brown. Confirm the specific suffix 'UB' corresponds to the 28-pin SOIC package variant. Check for RoHS compliance status and ensure the operating temperature range meets the application requirements of -40°C to +85°C before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7807UB when high-resolution 16-bit conversion is required alongside moderate-speed sampling up to 200 kSPS. The integrated reference simplifies design by reducing external component count. Choose this part over higher-speed variants if power efficiency is critical, as it offers lower power dissipation compared to faster ADCs in the same family.

Analog To Digital Converters (ADC) Part Context

The ADS7807 belongs to the ADS7807 series of low-power CMOS sampling ADCs. Originally developed by Burr-Brown, the product line was integrated into Texas Instruments following their acquisition. This specific model represents a balance between precision and power efficiency, suitable for applications requiring accurate data conversion without excessive energy usage.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same family include the ADS7805 and ADS7806, though these offer different resolutions or sampling rates. Verify interface compatibility and reference requirements when substituting with other SAR ADCs from Texas Instruments or third-party manufacturers.
