ADS7813U

Analog To Digital Converters (ADC) Overview

The ADS7813U is a low-power, serial output analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 16-bit resolution and utilizes a successive approximation register (SAR) architecture. The device operates with a single supply voltage ranging from 4.75 V to 5.25 V for both analog and digital domains. It supports a sampling rate of up to 40 kS/s and accepts single-ended input signals. The component communicates via an SPI-compatible serial interface and includes an internal reference voltage source. It is housed in a 16-pin SOIC package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal reference voltage to simplify external circuit design
• Supports standard SPI-compatible serial communication interfaces
• Operates on a single power supply for both analog and digital sections

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption
• Battery-powered data acquisition devices
• Industrial process control monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'U' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the ordering part number matches the required temperature grade and packaging format for your specific manufacturing requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and low power consumption are critical constraints. Compare against the ADS7813P if a DIP package is preferred over surface mount. Evaluate the ADS7817 series if differential inputs or higher sampling rates are required instead of single-ended inputs.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7813 family of low-power ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7813P but differs in physical packaging. The U suffix specifically denotes the small-outline integrated circuit (SOIC) form factor suitable for surface-mount technology applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7813PB is a pin-compatible alternative offering the same electrical specifications in a different package style. Verify that any substitute maintains the 4.75 V to 5.25 V supply requirement and SPI compatibility.
