MAX1080BCUP

Analog To Digital Converters (ADC) Overview

The MAX1080BCUP is a 10-bit successive-approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated. It integrates an 8-channel analog-input multiplexer, a high-bandwidth track/hold circuit, and a serial interface. Designed for single-supply operation, the MAX1080 operates from +4.5V to +5.5V and achieves a sampling rate of 400ksps. The device features an internal +2.5V reference with a buffer amplifier offering a ±1.5% adjustment range. It supports software-configurable unipolar or bipolar inputs and includes four selectable power modes to minimize current consumption in battery-powered applications.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Portable data logging systems
• Battery-powered instrumentation
• Medical instruments
• Process control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCUP against official documentation to confirm the commercial temperature range and lead-free status. Ensure the supply voltage matches the MAX1080 specifications (+4.5V to +5.5V). Confirm that the required sampling rate aligns with the 400ksps capability before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1080BCUP when eight analog channels are required within a single package. This component is suitable for designs needing a 10-bit resolution at up to 400ksps. Verify that the system supply voltage falls within the +4.5V to +5.5V range. Consider the internal reference if external precision references are not available.

Analog To Digital Converters (ADC) Part Context

The MAX1080BCUP belongs to the MAX1080/MAX1081 family of serial ADCs. It serves as a higher-speed alternative to the MAX148/MAX149 series. While the MAX1081 variant operates on lower voltages (+2.7V to +3.6V), the MAX1080 is optimized for standard 5V logic systems. Both share the same 20-pin TSSOP footprint and functional architecture.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1081BCUP is a direct pin-compatible substitute operating at lower voltages. For legacy replacements, the MAX148/MAX149 series offers similar functionality but at reduced speeds.
