ADS8699IPWR

Analog To Digital Converters (ADC) Overview

The ADS8699IPWR is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential, pseudo-differential, or single-ended input channel with a sampling rate of 100 kSPS. The device operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 1.65 V to 5.25 V. It utilizes an SPI interface for communication and includes an internal oscillator and programmable gain amplifier (PGA). The component is housed in a 16-TSSOP package and supports operation temperatures from -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Check for any recent product change notices regarding marking changes or material substitutions that may affect integration timelines.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 100 kSPS throughput are required for single-channel applications. Ensure the system design accommodates the separate analog and digital supply voltage ranges. Verify that the SPI interface timing aligns with the host microcontroller capabilities. Consider the thermal performance within the specified operating temperature range during PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS869x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with models like the ADS8691 and ADS8695 but offers specific resolution and feature combinations tailored for precision applications. The IPWR suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include the ADS8691 and ADS8695. Verify functional equivalence regarding resolution, sampling speed, and input configuration before substitution. Review updated datasheets for any differences in register maps or electrical characteristics that might require firmware adjustments.
