It samples at 133k samples per second over a dual ±5V supply, and communicates via MICROWIRE, QSPI, or SPI-compatible serial links. The through-hole PDIP footprint makes it a natural fit for prototyping, legacy system retrofits, and sockets in industrial or test equipment where board-level rework is expected. ## Industrial temperature range and dual-supply operation Rated from -40°C to 85°C, this ADC suits enclosures on the factory floor, outdoor base stations, or engine-bay-adjacent instrumentation where commercial-grade parts would drift or fail. The dual ±5V supply is a classic analog front-end rail — common in precision signal chains that need a clean bipolar swing. If your existing board only has a single 5V rail, you will need a DC-DC converter or charge pump to generate the negative supply; factor that into the BOM space and cost. ## Package and lifecycle — sourcing posture The MAX186AEPP+ is listed as Active and ROHS3 compliant, so there is no imminent last-time-buy or RoHS exemption expiry to track. The 20-pin PDIP package (0.300\" body width) is a through-hole legacy footprint that remains widely socketed in industrial and test equipment. For volume builds, qualify the order against a firm RFQ to lock lead time.","metaTitle":"MAX186AEPP+ 12-bit 8-channel DAS/ADC, 133k SPS, 20-DIP","metaDescription":"MAX186AEPP+ is a 12-bit, 8-channel data acquisition system ADC sampling at 133k SPS.

Verify the exact interface timing and supply requirements against your design before substituting."},{"question":"Is MAX186AEPP+ compatible with 5V microcontrollers?","answer":"Yes, the serial interface (MICROWIRE, QSPI, SPI) operates at logic levels compatible with 5V microcontrollers. The dual ±5V analog supply is separate from the digital interface, so no level shifting is needed for the SPI lines when connecting to a 5V MCU."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX186AEPP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX186AEPP when reusing this data.
