ADS8674IDBT

Analog To Digital Converters (ADC) Overview

The ADS8674IDBT is a quad-channel, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 500 kSPS and accepts single-ended inputs. The device features an internal 4.096 V reference and supports SPI digital interfaces. It functions within an analog supply range of 4.75 V to 5.25 V and a digital supply range of 1.65 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 85 dB, differential nonlinearity of 0.5 LSB, and integral nonlinearity of 0.75 LSB. Power consumption is rated at 65 mW, and it operates between -40°C and +125°C in a 38-pin TSSOP package.

• Data acquisition modules in harsh industrial environments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with required voltage levels and interface protocols before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent 14-bit channels are necessary within a single package. Consider the internal reference and PGA capabilities to reduce external component count. Verify that the 500 kSPS throughput meets the system bandwidth requirements and that the TSSOP-38 footprint fits the design constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS867x family of high-speed, low-power SAR ADCs from Texas Instruments. It shares architectural similarities with models like the ADS8678 but differs in channel count and pin configuration. The series is designed for applications demanding precision and speed in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8678IDBT serves as a functional alternative offering eight channels instead of four. Verify pinout compatibility and software register settings when substituting between these variants within the same product family.
