It samples at 480 SPS and includes a programmable gain amplifier (PGA) on-chip, which lets you amplify small differential signals before conversion without an external op-amp stage. The SPI data interface keeps the digital side simple — three or four wires to the host MCU. Typical applications include weigh scales, pressure sensors, temperature measurement, and portable instrumentation where 18-bit resolution and low-speed precision are the priority. ## 480 SPS and the noise trade-off The sigma-delta architecture oversamples the input and trades conversion rate for noise rejection. ## Separate analog and digital supply rails The analog supply runs from 2.7 V to 3.6 V; the digital supply accepts 1.7 V to 3.6 V. ## Industrial temperature range and package Rated for -40°C to 85°C, the MAX11209EEE+ fits industrial environments: factory-floor data acquisition, outdoor sensor nodes, and equipment that sees temperature swings. The 16-QSOP package (3.90 mm body width) is a compact footprint for space-constrained PCBs. It ships in Tube — the standard for low-volume prototyping and small production runs. ## Lifecycle and sourcing The MAX11209EEE+ is listed as Active and ROHS3 compliant. There is no end-of-life notice or last-time-buy window.","metaTitle":"MAX11209EEE+ 18-Bit Sigma-Delta ADC, SPI, 480 SPS, 16-QSOP","metaDescription":"MAX11209EEE+ 18-bit sigma-delta ADC from Analog Devices.

Connect it to your MCU's SPI bus with a chip-select line for each conversion result."},{"question":"Can MAX11209EEE+ be used in portable battery-powered devices?","answer":"Yes, the low 480 SPS sampling rate and the ability to power the digital section from 1.7 V to 3.6 V make it suitable for battery-operated designs. The PGA on-chip also reduces external component count, saving board space and power."},{"question":"Can MAX11209EEE+ be used in industrial temperature range?","answer":"Yes, the operating temperature range is -40°C to 85°C, which covers the industrial temperature grade. It is suitable for factory automation, outdoor sensors, and other industrial equipment."},{"question":"What is the closest pin-compatible alternative to MAX11209EEE+?","answer":"The MAX11209EEE+ is part of a family of pin-compatible sigma-delta ADCs from Analog Devices.
