ADS7808P

Analog To Digital Converters (ADC) Overview

The ADS7808P is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Burr-Brown. It features a single-channel serial output interface and operates on a single 5V supply. The device supports a maximum sampling rate of 100kHz with a typical conversion time of 10 microseconds. It offers a signal-to-noise plus distortion ratio (SNDR) of 72dB at a 45kHz input frequency. Maximum power consumption is rated at 100mW. The component utilizes internal or external reference options and is housed in a PDIP-20 package, operating within a temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific manufacturing source and date code upon procurement, as the ADS7808P is listed among discontinued products by Texas Instruments. Ensure compatibility with existing system designs given the component's end-of-life status. Confirm package integrity and pinout alignment with legacy documentation before integration into new production runs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit ADC with serial output is required for moderate-speed applications up to 100kSPS. It is suitable for designs needing low power operation from a single 5V supply. Consider availability constraints due to its discontinued status and evaluate alternative successors if long-term supply stability is critical for the project lifecycle.

Analog To Digital Converters (ADC) Part Context

The ADS7808P belongs to the Burr-Brown family of CMOS analog-to-digital converters. It is part of a series that includes variants like the ADS7809P. The device is designed for general-purpose data acquisition tasks where moderate speed and high resolution are balanced against power efficiency. Its PDIP-20 packaging facilitates through-hole mounting in traditional circuit board layouts.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7808P is listed as a discontinued product. Users should consult official replacement guides for compatible successors such as the ADS7809P or other modern 12-bit serial ADCs from Texas Instruments. Verify pinout and functional compatibility before substituting.
