ADS7813UG4

Analog To Digital Converters (ADC) Overview

The ADS7813UG4 is a low-power, serial interface analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 16-bit resolution and operates with a single-ended input configuration. The device utilizes a successive approximation register (SAR) architecture and supports an SPI-compatible serial interface. It functions within an analog and digital supply voltage range of 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, and a power dissipation of 35 mW. The component is housed in a 16-pin SOIC package and includes an internal reference.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the official Texas Instruments datasheet to confirm it denotes lead-free packaging compliance without altering electrical characteristics. Ensure the ordering part number matches the exact package style required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm current production status and availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and moderate speed are required for single-channel applications. It is suitable for designs constrained by power consumption limits due to its low dissipation rating. Verify that the system requires a single-ended input and can accommodate the specified supply voltage range. Confirm compatibility with the target microcontroller's SPI interface timing requirements.
