It is designed for industrial sensor applications where multiple analog signals must be digitized and transmitted over a reduced pin count to a host controller. The device operates from a single supply and draws 1.4 mA typical, making it suitable for power-sensitive remote sensor modules. Its -40°C to 125°C operating temperature range covers factory-floor, outdoor telecom, and under-hood automotive environments. ## Package and thermal considerations The MAX31911AUI+T is housed in a 28-TSSOP package with an exposed pad (28-TSSOP-EP). The exposed pad must be soldered to a thermal land on the PCB to achieve the rated thermal performance. In a rework or repair scenario, the exposed pad requires a hot-air profile with bottom-side preheat to avoid cold joints. The package footprint is 4.40 mm width, 0.173\" body length, standard for TSSOP-28. ## Lifecycle and sourcing reality The MAX31911AUI+T carries an Active lifecycle status per the manufacturer. It is ROHS3 compliant. There is no indication of a last-time-buy or end-of-life notice. No official second-source or pin-compatible replacement is listed in the available records.","metaTitle":"MAX31911AUI+T Serializer, SPI, 28-TSSOP-EP, -40°C to 125°C","metaDescription":"MAX31911AUI+T Serializer from Analog Devices.
