ADS7807UG4

Analog To Digital Converters (ADC) Overview

The ADS7807UG4 is a low-power, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a sampling rate of 200 kSPS and utilizes a CMOS architecture with a Successive Approximation Register (SAR) structure. The device supports both parallel and serial interfaces for data output. It operates on a single 5V supply, drawing only 10 mW of power during conversion. Key electrical specifications include an input voltage range of 0 to VREF, a reference voltage of 5V, and a signal-to-noise ratio (SNR) of 93 dB. The component is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal reference voltage source eliminates the need for external components.
• Dual interface capability supporting both parallel and synchronous serial communication protocols.
• Low-power consumption design suitable for battery-operated applications.
• High-resolution 16-bit accuracy with fast 200 kSPS sampling throughput.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring high precision and low power.
• Industrial process control loops with isolated measurement channels.
• Medical equipment such as patient monitors and diagnostic devices.
• Data acquisition systems for environmental sensing and monitoring.

Analog To Digital Converters (ADC) Procurement Notes

Verify the RoHS compliance status and specific suffix codes before ordering, as manufacturing sources may vary. Confirm availability through authorized distributors, noting that older revisions might be discontinued or subject to long lead times. Ensure the package type matches the PCB footprint requirements exactly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and 200 kSPS speed are required within a single-channel SAR ADC framework. Compare against the ADS7805 if lower speed is acceptable, or the ADS7809 for higher throughput. Consider the integrated reference feature to reduce bill-of-materials complexity compared to discrete reference solutions.

Analog To Digital Converters (ADC) Part Context

The ADS7807 belongs to the Burr-Brown acquired family of high-performance data converters now managed by Texas Instruments. It represents a legacy product line known for robust performance in precision measurement applications. Engineers often encounter this part in existing designs requiring stable, high-resolution analog-to-digital conversion without complex external circuitry.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may be limited due to the specific combination of 16-bit resolution and dual interface options. Review the ADS7805 for lower-speed needs or ADS7809 for faster sampling. Verify interface compatibility and reference voltage requirements when substituting with newer Texas Instruments ADC families.
