ADS7866IDBVT

Analog To Digital Converters (ADC) Overview

The ADS7866IDBVT is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter 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 200 kSPS and features a serial SPI-compatible interface. Key electrical specifications include a signal-to-noise ratio of 71 dB, integral nonlinearity of +/- 1.5 LSB, and differential nonlinearity of -1/1.5 LSB. It consumes 220 uW of power at the minimum supply voltage and 1.8 mW at maximum. 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) Procurement Notes

Verify the specific ordering suffix IDBVT corresponds to the SOT-23-6 package and tape-and-reel delivery format. Confirm that the device meets RoHS compliance requirements for the intended market. Ensure the design accounts for the specified humidity sensitivity level during storage and reflow soldering processes. Validate that the selected supplier provides authentic components traceable to Texas Instruments manufacturing records.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 200 kSPS throughput are required in a minimal footprint. It is suitable for designs constrained by low voltage supplies down to 1.2 V. Consider alternative packages if thermal dissipation exceeds limits or if higher pin counts are needed for additional functionality. Evaluate system noise requirements against the 71 dB SNR specification before finalizing the architecture.

Analog To Digital Converters (ADC) Part Context

The ADS7866 belongs to the microPOWER family of data converters from Texas Instruments. This series focuses on balancing performance with ultra-low power consumption for portable devices. The IDBVT designation specifically identifies the industrial temperature grade variant packaged in a compact SOT-23-6 outline, distinguishing it from other pinouts or temperature ranges within the broader ADS7866 product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include ADS7866 variants with different packaging or temperature ratings. Cross-reference with ADS7866IDBVR for reel-based procurement needs. Verify compatibility with ADS7866EVM development kits for validation purposes.
