ADS8325IDGKTG4

Analog To Digital Converters (ADC) Overview

The ADS8325IDGKTG4 is a 16-bit successive approximation register analog-to-digital converter manufactured by Texas Instruments. It features a serial interface compatible with standard SPI and QSPI protocols, supporting sampling rates up to 100 ksps. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It integrates an internal low-drift reference and a track-and-hold amplifier. The component is housed in an 8-pin VSSOP package and supports operation across an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'TG4' against the manufacturer's official documentation to confirm RoHS compliance and lead-free status. Ensure the ordering part number matches the exact package variant and temperature grade required for the design. Cross-reference the datasheet revision history to confirm pinout compatibility and electrical characteristics before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 100 ksps throughput are required in a compact surface-mount package. Compare performance metrics such as input noise and total unadjusted error against alternative SAR ADCs if higher speed or lower power is needed. Verify that the system voltage levels align with the 2.7 V to 5.5 V operating range and that the serial interface timing meets the microcontroller requirements.

Analog To Digital Converters (ADC) Part Context

The ADS8325 belongs to Texas Instruments' family of 16-bit high-speed analog-to-digital converters. It shares architectural similarities with other members like the ADS8326 but offers specific trade-offs in sampling rate and power consumption. The IDGKTG4 designation indicates a tape-and-reel packaging format intended for automated assembly processes in high-volume manufacturing environments.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8326IDGKR is a documented pin-compatible alternative within the same product family, offering a higher sampling rate of 200 ksps. Designers should verify that the increased speed does not exceed system clock capabilities and that power dissipation remains within thermal limits when substituting this part.
