Three on-chip features handle the common use cases: One-Shot mode for a single conversion on demand (saves power between reads), programmable resolution to trade conversion time against noise, and a shutdown mode that drops quiescent current to near zero when the system is idle. The SPI interface is straightforward — no I2C address conflicts, no pull-up resistors needed. ## Where it fits — and what the ratings mean for your BOM The ±2°C accuracy is typical for a general-purpose digital sensor. The 8-SOIC package is a standard footprint — same land pattern as an SOIC-8 op-amp or EEPROM. No board respin needed if you are replacing a similar SPI temp sensor in the same package. ## Lifecycle and compliance — no surprises No last-time-buy notice, no NRND flag. ROHS3 compliant, so it passes EU and most global environmental requirements without an exemption declaration.","metaTitle":"Maxim DS1722S+ Digital Temperature Sensor, SPI, 11-bit","metaDescription":"Maxim DS1722S+ digital local temperature sensor with SPI output, 11-bit resolution, ±2°C accuracy.
