ADS7868IDBVR

Analog To Digital Converters (ADC) Overview

The ADS7868IDBVR is a single-channel, 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates within 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 utilizes a serial peripheral interface (SPI) for data communication. Key performance metrics include a signal-to-noise ratio of 49.8 dB, with differential and integral nonlinearity specified at +/- 0.5 LSB. Power consumption is rated at 220 uW, with a maximum power dissipation of 1.8 mW. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel configuration matches production requirements. Confirm that the component meets RoHS compliance standards for the target market. Check humidity sensitivity levels and storage conditions prior to assembly to prevent moisture-related damage during reflow soldering processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed are sufficient for the application. Consider the 1.2 V minimum supply voltage for low-voltage designs. Ensure the SPI interface timing aligns with the host microcontroller capabilities. Evaluate the thermal performance within the enclosed system environment given the small package size.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7868 family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other SAR converters in the series but is distinguished by its specific 8-bit resolution and 280 kSPS throughput. The IDBVR suffix indicates the industrial temperature grade and the specific SOT-23-6 reel packaging format used for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7868IDBVT is the tape-and-reel variant of the same functional device.
