ADS7813UB

Analog To Digital Converters (ADC) Overview

The ADS7813UB 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 single-ended input configurations. The device utilizes a serial SPI interface for data communication. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) and SINAD of 89 dB, along with differential and integral nonlinearity specifications of 2 LSB. The component is housed in an SOIC-16 package and is designed for operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel options. Confirm RoHS compliance status as manufacturing processes may evolve. Check for active production status or obsolescence notices directly from Texas Instruments documentation before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and low power consumption are critical requirements. Ensure the application supports single-ended inputs rather than differential signals. Verify that the system clock speed aligns with the 40 kS/s maximum sampling rate constraint. Confirm compatibility with the required SPI mode and voltage levels for the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7813 series of low-power serial ADCs. It shares architectural similarities with other members like the ADS7817 but offers higher resolution at lower speeds. The UB suffix typically denotes the SOIC-16 surface-mount package variant within the broader product family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS7813U. For different resolutions or speeds, consider the ADS7817 series for faster sampling or the ADS7816 for alternative interface options. Always verify pinout compatibility and electrical specifications before substitution.
