MAX186CCPP+

ADCs/DACs - Special Purpose Overview

The MAX186CCPP+ is a 12-bit, 8-channel data acquisition system (DAS) and analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuit, and serial interface with successive-approximation conversion architecture. The device operates on a single +5V or dual ±5V supply, consuming 1.5mA in operating mode and under 10µA in power-down modes. It features an internal 4.096V reference, software-configurable unipolar/bipolar and single-ended/differential inputs, and a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The component is housed in a 20-pin PDIP package and supports a sampling rate of 133ksps.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific grade suffix 'C' corresponds to the required temperature range of 0°C to +70°C. Confirm the '+'' suffix indicates lead-free/RoHS compliance. Ensure the 20-pin PDIP package matches the target PCB footprint. Check for availability of evaluation kits if hardware validation is required during development.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX186 variant over MAX188 when an internal 4.096V reference is desired to simplify external component count. Choose this part for applications requiring low power consumption with quick turn-on times between conversions. Ensure the serial clock frequency does not exceed 2MHz in external clock mode to maintain specified timing characteristics. Verify that the source impedance of analog inputs remains below 5kΩ or use appropriate filtering to meet acquisition time requirements.

ADCs/DACs - Special Purpose Part Context

The MAX186/MAX188 series are low-power, 8-channel, serial 12-bit ADCs designed for data-acquisition systems. The MAX186 includes an internal reference, while the MAX188 requires an external reference. Both share identical pinouts and functionality except for the reference configuration. The MAX186CCPP+ specifically denotes the commercial temperature grade (0°C to +70°C) in a 20-pin plastic dual in-line package.
