MAX186CCAP+T

ADCs/DACs - Special Purpose Overview

The MAX186CCAP+T is a 12-bit, 8-channel analog-to-digital converter (ADC) from the MAX186/MAX188 family. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuit, and serial interface. The device operates on a single +5V or dual ±5V supply and supports software-configurable unipolar/bipolar and single-ended/differential inputs. Key electrical parameters include a 133ksps sampling rate, internal 4.096V reference, and low power consumption of 1.5mA in operating mode. It features a 4-wire serial interface compatible with SPI, QSPI, Microwire, and TMS320 DSPs.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution with 8 single-ended or 4 differential input channels
• Internal 4.096V reference voltage and reference-buffer amplifier
• Low power: 1.5mA operating current, 2µA full power-down current
• Software-selectable unipolar/bipolar and single-ended/differential modes

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging when sourcing this specific part number. Confirm the 'C' grade designation corresponds to the required accuracy specifications for your application. Ensure compatibility with the 20-pin SSOP package dimensions for PCB layout.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX186 variant if an internal 4.096V reference is desired; choose MAX188 for external reference requirements. Consider the 'E' grade (-40°C to +85°C) if operation outside the commercial temperature range (0°C to +70°C) is needed. Verify that the source impedance is below 5kΩ or use input capacitors to maintain acquisition time integrity.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX186/MAX188 series of low-power, serial 12-bit ADCs. The MAX186 includes an internal reference, while the MAX188 requires an external one. Both share identical pinouts and functionality except for the reference configuration. The CCAP+ designation specifies the C-grade performance level in a 20-pin SSOP package with lead-free/RoHS compliance.

ADCs/DACs - Special Purpose Replacement Considerations

Direct functional substitutes within the same package include other grades of the MAX186 (e.g., MAX186CAP+) or the MAX188 (MAX188CAP+) if external references are used. Cross-family replacements require verification of pin compatibility and serial interface timing.
