MAX1107CUB+

Analog To Digital Converters (ADC) Overview

The MAX1107CUB+ is a single-channel, 8-bit successive-approximation analog-to-digital converter (ADC) designed for low-power applications. It operates on a single supply voltage ranging from +4.5V to +5.5V and consumes only 107µA at a conversion rate of 25ksps. The device integrates an internal track/hold circuit, a 4.096V voltage reference, and a clock. It features a pin-selectable power-down mode that reduces current consumption to 0.5µA. The component utilizes a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. It is housed in a compact 10-pin µMAX package.

• Medical instruments
• Solar-powered remote systems
• Receive-signal-strength indicators

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CUB+' against official Analog Devices documentation to confirm the commercial temperature range and lead-free status. Ensure the ordering part number matches the exact package type and thermal grade required for your design. Cross-reference the manufacturer's latest datasheet revision to validate all electrical specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1107CUB+ when a single-supply operation between +4.5V and +5.5V is required. This component is suitable for designs needing 8-bit resolution at speeds up to 25ksps with low power consumption. Consider the integrated reference if external components must be minimized. Verify that the serial interface timing aligns with the host microcontroller's capabilities.

Analog To Digital Converters (ADC) Part Context

The MAX1107 is part of the MAX1106/MAX1107 family of low-power, serial ADCs. While the MAX1106 operates on a lower voltage range (+2.7V to +3.6V), the MAX1107 is optimized for standard +5V systems. Both share similar architectural features but differ in supply voltage specifications and internal reference voltages. The CUB+ designation indicates a specific package and environmental compliance variant within this product line.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1106CUB+ serves as a voltage-compatible alternative if the system operates within the +2.7V to +3.6V range. Designers should verify that the supply voltage requirements and internal reference levels match the new component's specifications before substitution.
