ADS7807P

Analog To Digital Converters (ADC) Overview

The ADS7807P is a low-power, 16-bit sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and supports single-ended input signals. The device operates with both analog and digital supply voltages ranging from 4.75 V to 5.25 V. Key performance metrics include a maximum sampling rate of 40 kS/s, a signal-to-noise ratio (SNR) of 88 dB, and a differential nonlinearity (DNL) of -2/3 LSB. Power consumption is specified at 28 mW during operation. It features parallel and SPI interface options and is housed in a PDIP-16 package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal reference voltage option alongside external reference capability for flexible system design.
• Supports both parallel and serial (SPI) digital interfaces for versatile microcontroller connectivity.
• Low power consumption design suitable for battery-operated or energy-efficient applications.
• High resolution with 16-bit accuracy and low nonlinearity errors for precise data acquisition.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring high resolution and low power.
• Industrial process control systems with single-ended sensor inputs.
• Data acquisition systems utilizing microcontrollers with SPI or parallel buses.
• Medical equipment needing accurate analog signal digitization.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'P' indicates the PDIP-16 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure supply chain sources provide genuine Texas Instruments components to guarantee performance specifications and reliability standards are met for critical applications.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7807P when a 16-bit resolution and 40 kS/s sampling rate are required for single-channel applications. Consider this component if the system design mandates a 5V supply domain and offers flexibility between parallel and serial communication interfaces. Evaluate power constraints against the 28 mW typical consumption to ensure compatibility with thermal and energy budgets.

Analog To Digital Converters (ADC) Part Context

The ADS7807P belongs to the ADS7807 series of precision ADCs from Texas Instruments. This series is designed for applications demanding high accuracy and low power consumption. The 'P' suffix specifically denotes the plastic dual-in-line package (PDIP), distinguishing it from surface-mount variants like the U (SOIC) or N (TSSOP) packages within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package may include other members of the ADS7807 family such as the ADS7807U or ADS7807N, provided the package type matches the PCB footprint. Verify electrical parameters and interface compatibility before substituting with devices from different manufacturers or families.
