MAX186CEAP+

ADCs/DACs - Special Purpose Overview

The MAX186CEAP+ is a low-power, 8-channel, serial 12-bit analog-to-digital converter (ADC) in a 20-pin SSOP package. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuit, and successive-approximation architecture. The device operates on a single +5V or dual ±5V supply with a sampling rate of 133ksps. It features an internal 4.096V reference, software-configurable unipolar/bipolar inputs, and a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Operating temperature range is -40°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution with 133ksps sampling rate
• 8-channel single-ended or 4-channel differential inputs
• Internal 4.096V reference and reference-buffer amplifier
• Software-selectable power-down modes reducing current to under 10µA

ADCs/DACs - Special Purpose Applications

• Portable data logging systems
• High-accuracy process control
• Automatic testing equipment
• Battery-powered instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific grade suffix 'C' for electrical characteristics against the datasheet. Confirm the 'AP+' suffix indicates the SSOP package and lead-free/RoHS compliance. Ensure the operating environment falls within the specified -40°C to +85°C range.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring low power consumption and multiple analog inputs. The MAX186 includes an internal reference, whereas the MAX188 requires an external one. Choose between internal or external clock modes based on system timing requirements and processor capabilities.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX186/MAX188 family of low-power, 8-channel, serial 12-bit ADCs. The 'C' grade specifies DC accuracy parameters, while the 'E' grade covers extended temperature ranges. The 'AP+' designation identifies the shrink small-outline package variant.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX186CCAP+ is a commercial grade equivalent with a 0°C to +70°C range. The MAX186CEWP+ offers the same electrical performance in an SOIC-20 package instead of SSOP.
