MAX186BCPP+

ADCs/DACs - Special Purpose Overview

The MAX186BCPP+ is a 12-bit, 8-channel data-acquisition system manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuit, and serial interface with ultra-low power consumption. The device operates on a single +5V or dual ±5V supply and supports software-configurable unipolar/bipolar and single-ended/differential inputs. It features a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The part includes an internal 4.096V reference and is housed in a 20-pin PDIP package with an operating temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific grade suffix 'B' against the manufacturer's electrical characteristics table for accuracy specifications. Confirm the '+C' suffix indicates lead-free/RoHS compliance and the 'P' suffix denotes the 20-pin PDIP package type. Ensure the operating environment stays within the specified 0°C to +70°C temperature range for this variant.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX186BCPP+ when an internal reference is required, distinguishing it from the MAX188 series which needs an external reference. Choose the 'B' grade for specific DC accuracy requirements defined in the datasheet. Consider the 20-pin PDIP package for through-hole mounting applications requiring wider pin spacing compared to SO or SSOP variants.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX186/MAX188 family of low-power, serial 12-bit ADCs. The MAX186 variant is distinguished by its integrated 4.096V reference, whereas the MAX188 requires an external reference source. Both share identical architecture, including the 8-channel multiplexer and serial interface capabilities.
