ADS8698IDBT

Analog To Digital Converters (ADC) Overview

The ADS8698IDBT is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It integrates eight single-ended inputs, a programmable gain amplifier, a multiplexer, and a track-and-hold circuit within a single device. The component operates with an analog supply voltage of 5V and a digital supply range of 1.65V to 5.25V. It supports a maximum sampling rate of 500k samples per second and communicates via an SPI interface. The device is housed in a 38-TSSOP package and functions within a temperature range of -40°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IDBT corresponds to the tube packaging configuration as listed in official distributor catalogs. Confirm that the 38-TSSOP footprint matches the target PCB layout dimensions. Ensure the selected variant meets the required operating temperature range for the intended environment. Cross-reference the manufacturer part number with current datasheets to validate pinout compatibility before integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an application demands high resolution across multiple channels without external multiplexing complexity. The integrated PGA reduces the need for additional amplification stages. Consider the 500ksps throughput limit against system bandwidth requirements. Evaluate the 1.65V to 5.25V digital supply flexibility for interfacing with various logic levels in mixed-voltage systems.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS869x family of high-speed, low-power ADCs from Texas Instruments. The ADS8698 specifically offers eight channels, distinguishing it from lower-channel variants like the ADS8694. It serves as a complete analog front-end solution, combining conversion, conditioning, and selection capabilities into a single integrated circuit for efficient board space utilization.
