8-bit SAR ADC in a TSOT-23-6 — what the ratings mean for the BOM
The AD7278BUJZ-500RL7 is an 8-bit successive-approximation-register (SAR) analog-to-digital converter from Analog Devices, sampling at 3 MSPS from a single-ended input. 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.
