Product details

12-bit, 8-channel data acquisition system in a 20-pin DIP

The Maxim Integrated MAX186AEPP+ is a complete 12-bit data acquisition system (DAS) that integrates an 8-channel multiplexer, a successive-approximation ADC, and a serial interface in a single 20-pin DIP package. It samples at 133k samples per second over a dual ±5V supply, and communicates via MICROWIRE, QSPI, or SPI-compatible serial links.

Industrial temperature range and dual-supply operation

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 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.

Frequently asked questions

Is MAX186AEPP+ obsolete or EOL?

No, the MAX186AEPP+ is listed as Active with ROHS3 compliance. There is no discontinuation notice or last-time-buy window in effect.

What is the equivalent of MAX186AEPP+?

A direct pin-compatible alternative within the same Maxim family is the MAX187AEPP+, which offers a similar 12-bit DAS/ADC in the same 20-DIP footprint but with a higher sampling rate. Verify the exact interface timing and supply requirements against your design before substituting.

Is MAX186AEPP+ compatible with 5V microcontrollers?

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.
