ADS7867IDBVR

Analog To Digital Converters (ADC) Overview

The ADS7867IDBVR is a single-channel, 10-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 240 kSPS and features a serial interface compatible with standard SPI protocols. Key performance metrics include a signal-to-noise ratio of 61.8 dB, with differential and integral nonlinearity specified at +/- 0.5 LSB. Power consumption is rated at 220 uW during operation and 1.8 mW peak dissipation. It functions within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-6 surface-mount package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'DBVR' confirms the SOT-23-6 package and reel packaging format. Ensure compatibility with the required 1.2 V to 3.6 V supply rails. Confirm that the serial interface timing meets the system's clock requirements. Check for moisture sensitivity level handling procedures if storage conditions exceed manufacturer guidelines. Validate that the 10-bit resolution and 240 kSPS speed meet the application's accuracy and bandwidth needs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of low power, moderate speed, and small footprint is required. The 10-bit resolution is sufficient for many general-purpose sensing applications. Consider the single-ended input configuration and ensure it matches the source impedance. Verify that the SPI interface logic levels are compatible with the host microcontroller. Evaluate thermal performance given the small package size under continuous operation.

Analog To Digital Converters (ADC) Part Context

The ADS7867 belongs to Texas Instruments' family of low-power, high-speed ADCs. It is designed to replace older, higher-voltage, or larger-package converters in modern portable electronics. The IDBVR variant specifically denotes the industrial temperature grade and the tape-and-reel shipping format. It complements other TI devices like the ADS7866 and ADS7868, which offer similar performance with slight variations in resolution or channel count.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may include the ADS7866IDBVR or ADS7868IDBVR, depending on required resolution and channel count. Verify that substitute parts maintain the same 1.2 V to 3.6 V operating voltage range and SPI compatibility. Ensure thermal and mechanical specifications match the existing board layout.
