MAX186CCAP+

ADCs/DACs - Special Purpose Overview

The MAX186CCAP+ is a 12-bit data-acquisition system integrating an 8-channel multiplexer, track/hold circuit, and serial interface. It operates on a single +5V or dual ±5V supply with a sampling rate of 133ksps. The device features an internal 4.096V reference and supports unipolar/bipolar and single-ended/differential inputs via a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE. It consumes 1.5mA in operating mode and utilizes a 20-SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'CAP+' indicates the SSOP package and lead-free/RoHS compliance. Confirm the temperature range corresponds to the 'C' grade (0°C to +70°C). Ensure the specific revision matches current manufacturing standards.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring low power consumption and high accuracy. The internal reference simplifies design compared to the MAX188 variant. Verify that the 133ksps speed meets system requirements and that the serial interface timing aligns with the host microcontroller.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX186/MAX188 family of low-power, 8-channel, serial 12-bit ADCs. The MAX186 variant includes an internal reference, whereas the MAX188 requires an external one. Both share identical pinouts and functionality except for the reference configuration.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX186CEWP+ offers the same electrical specifications in a 20-SOIC package. The MAX186CPP+ provides the same performance in a 20-PDIP package. These are direct pin-compatible alternatives within the same series.
