ADS7868IDBVT

Analog To Digital Converters (ADC) Overview

The ADS7868IDBVT is a single-channel, 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with an analog and digital supply voltage range of 1.2 V to 3.6 V. The device supports a maximum sampling rate of 280 kSPS and features a serial peripheral interface (SPI) compatible with standard modes. It exhibits a signal-to-noise ratio (SNR) of 49.8 dB, with differential nonlinearity (DNL) and integral nonlinearity (INL) both specified at +/- 0.5 LSB. The component is housed in a SOT-23-6 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Compact SOT-23-6 surface-mount packaging designed for space-constrained applications.
• Low-power operation suitable for battery-powered systems with minimal power dissipation.
• Integrated SAR architecture providing fast conversion speeds without external clock requirements.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power consumption
• Battery-operated data acquisition systems
• Industrial process control sensors

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDBVT against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the ordering part number matches the required temperature grade and package variant. Cross-reference the manufacturer's latest documentation to validate current production status and any potential design changes or obsolescence notices before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 280 kSPS sampling rate are sufficient for the application. It is appropriate for designs requiring a single-ended input and SPI interface within a 1.2 V to 3.6 V supply range. Consider the SOT-23-6 package constraints for PCB layout and thermal management. Compare performance metrics against higher-resolution alternatives if precision requirements exceed 8 bits.

Analog To Digital Converters (ADC) Part Context

The ADS7868IDBVT belongs to the ADS7868 family of high-speed, low-power ADCs from Texas Instruments. This series includes variants such as the ADS7867 and ADS7866, which offer different resolutions and sampling rates while maintaining similar interface and package characteristics. The IDBVT suffix specifically denotes the SOT-23-6 package with tape-and-reel delivery, distinguishing it from other packaging options like the DBV or DBVR variants.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7868IDBVR is a pin-compatible alternative within the same family, differing primarily in packaging format. Verify electrical specifications and operating conditions remain identical before substitution. No other direct substitutes are confirmed in the provided documentation.
