ADS7807U/1K

Analog To Digital Converters (ADC) Overview

The ADS7807U/1K is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 40 kS/s and supports both parallel and SPI serial interfaces. The device functions on a single 5 V supply, with analog and digital power voltages ranging from 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 88 dB and a signal-to-noise and distortion ratio (SINAD) of 88 dB. Differential nonlinearity is specified at -2/3 LSB, while integral nonlinearity is +/- 3 LSB. It consumes 28 mW of power and operates within a temperature range of -40°C to +85°C in an SOIC-28 package.

Analog To Digital Converters (ADC) Feature Summary

• Supports dual interface modes including parallel data bus and standard SPI serial communication for flexible system integration.
• Features internal reference options alongside external reference capability to accommodate various input voltage ranges.
• Delivers high precision with 16-bit resolution and low power consumption suitable for battery-operated applications.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Portable instrumentation where low power consumption and single-supply operation are critical.
• Vibration monitoring and acoustic sensing applications utilizing the device's high SNR capabilities.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1K' indicates reel packaging when ordering. Confirm that the SOIC-28 package variant matches the target PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C range. Check for moisture sensitivity level requirements during storage and handling. Validate that the 40 kS/s sampling rate meets the bandwidth needs of the application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and 40 kS/s speed are required with minimal power draw. Consider the ADS7809U/1K if a higher 100 kS/s sampling rate is needed, noting it lacks the parallel interface option found in the ADS7807. Choose the ADS7804U/1K if only 12-bit resolution is sufficient for lower cost or reduced complexity. Ensure the single-ended input type aligns with the sensor output configuration.

Analog To Digital Converters (ADC) Part Context

The ADS7807 belongs to the ADS78xx family of low-power, high-speed ADCs from Texas Instruments. This series is designed for applications demanding precision and efficiency. The U/1K designation specifies the SOIC-28 surface-mount package and tape-and-reel quantity. It complements other devices like the ADS7805 and ADS7809 in the portfolio, offering a balance between resolution, speed, and interface flexibility.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7809U/1K offers 100 kS/s speed but lacks parallel interface. ADS7805U/1K provides 16-bit resolution at 100 kS/s with parallel interface. ADS7804U/1K is a 12-bit alternative with 100 kS/s speed. Verify pin compatibility and software driver adjustments for interface differences.
