It operates from a single 2.35 V to 3.6 V supply on both the analog and digital rails, and communicates over an SPI/DSP-compatible serial interface. The part is housed in a TSOT-23-6 package and rated for the -40°C to 125°C temperature range, making it suitable for industrial sensor interfaces, motor-feedback loops, and under-hood automotive data acquisition where board space is tight and the environment is harsh. ## 3 MSPS throughput — what it buys you The SAR architecture samples at 3 MSPS with no pipeline delay, so the controller sees the value at the conversion-start command. ## Package and footprint — TSOT-23-6 The TSOT-23-6 is a surface-mount package. The supplier device package is TSOT-6. ## Lifecycle and sourcing The part is Active with ROHS3 compliance. The AD7276BUJZ-500RL7 is pin-compatible and shares the same 3 MSPS rate, supply range, and package.","metaTitle":"AD7278BUJZ-500RL7 8-Bit SAR ADC, 3 MSPS, TSOT-23-6","metaDescription":"ADI AD7278BUJZ-500RL7 8-bit SAR ADC, 3 MSPS sampling, single-ended input, SPI/DSP interface, 2.35V-3.6V supply, -40°C to 125°C, TSOT-23-6.
