MAX186CEAP

ADCs/DACs - Special Purpose Overview

The MAX186CEAP is a low-power, 8-channel, serial 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuitry, and a successive-approximation ADC core. The device operates on a single +5V or dual ±5V supply with a sampling rate of 133ksps. Key electrical parameters include a resolution of 12 bits, an internal 4.096V reference voltage, and a small-signal bandwidth of 4.5MHz. It supports unipolar/bipolar and single-ended/differential input configurations via a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

ADCs/DACs - Special Purpose Feature Summary

• Integrates an 8-channel multiplexer and high-bandwidth track/hold for data acquisition.
• Features an internal 4.096V reference and software-configurable unipolar/bipolar inputs.
• Supports 4-wire serial interfaces including SPI, QSPI, and MICROWIRE without external logic.
• Operates in single +5V or dual ±5V supplies with ultra-low power consumption.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific package variant, as the CEAP suffix denotes the SSOP package. Confirm the temperature grade corresponds to the C designation (0°C to +70°C). Ensure the ordering suffix includes the '+' symbol if lead-free/RoHS compliance is required. Cross-reference the manufacturer's part numbering system to confirm availability and exact pinout compatibility.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX186CEAP when an integrated 8-channel solution with a serial interface is required. Choose this model over the MAX188 if an internal reference is preferred, as the MAX188 requires an external reference. Consider the SSOP package dimensions for space-constrained PCB layouts. Verify that the source impedance of the analog inputs is below 5kΩ to maintain optimal AC performance without additional filtering components.

ADCs/DACs - Special Purpose Part Context

The MAX186/MAX188 series are 12-bit data-acquisition systems designed for low-power applications. The MAX186 variant distinguishes itself by including an internal 4.096V reference, whereas the MAX188 relies on an external reference. Both share identical architectures regarding the multiplexer, track/hold, and serial interface capabilities.
