ADS7813P

Analog To Digital Converters (ADC) Overview

The ADS7813P is a low-power, serial 16-bit analog-to-digital converter manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a single-ended input type and SPI interface. The device operates on an analog and digital supply voltage ranging from 4.75 V to 5.25 V. Key performance metrics include a sampling rate of 40 kS/s, a signal-to-noise ratio (SNR) of 85 dB, differential nonlinearity (DNL) of 3 LSB, and integral nonlinearity (INL) of +/- 3 LSB. Power dissipation is specified at 35 mW. It includes an internal reference and functions within a temperature range of -40 C to +85 C, housed in a DIP-16 package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit SAR ADC core for high-resolution data conversion.
• Features a built-in internal voltage reference to simplify circuit design.
• Supports serial communication via a standard SPI-compatible interface.
• Designed for low-power operation suitable for battery-driven applications.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring high resolution and low power consumption.
• Industrial process control loops utilizing single-ended sensor inputs.
• Data acquisition modules for environmental monitoring equipment.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'P' corresponds to the PDIP-16 package variant when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 40 kS/s sampling speed are required for single-ended signals. The internal reference eliminates the need for external precision voltage sources. Consider the DIP-16 package constraints if PCB space allows for through-hole mounting. Verify that the 4.75 V to 5.25 V supply range aligns with the system's power architecture.

Analog To Digital Converters (ADC) Part Context

The ADS7813P belongs to the ADS7813 series of low-power serial ADCs from Texas Instruments. This family provides 16-bit resolution with varying package options such as the SOIC-16 (ADS7813U). The series is designed for applications balancing precision with power efficiency, offering a trade-off between speed and resolution compared to higher-speed pipeline converters.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7813U is a documented alternative within the same series, offering identical electrical characteristics but in an SOIC-16 surface-mount package. Verify pin compatibility and thermal requirements when substituting between DIP and SOIC packages.
