MAX1177ACUP+

Analog To Digital Converters (ADC) Overview

The MAX1177ACUP+ is a 16-bit successive-approximation analog-to-digital converter (ADC) featuring an automatic power-down mode, a factory-trimmed internal clock, and a byte-wide parallel interface. It operates from a single +4.75V to +5.25V analog supply and interfaces directly with +2.7V to +5.25V digital logic. The device accepts an analog input voltage range of 0 to +10V. Power consumption is no more than 26.5mW at a sampling rate of 135ksps using an external reference, and 31mW when utilizing the internal +4.096V reference. AutoShutdown reduces supply current to 0.5µA at 10ksps. It is available in a 20-pin TSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific AC suffix indicates the commercial temperature range (0°C to +70°C). Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high DC accuracy and low power consumption. Ensure the system design accommodates the separate analog and digital supply requirements. Verify that the parallel interface timing aligns with the host microcontroller's capabilities. Consider the 12ms wake-up time if utilizing the shutdown mode with the internal reference.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1177 family of 16-bit, 135ksps single-supply ADCs. The AC suffix specifically denotes the commercial temperature range variant. Other variants include the AEUP and BEUP models which support extended temperature ranges (-40°C to +85°C). All share the same core architecture and 20-pin TSSOP footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the MAX1177BCUP+ and MAX1177CCUP+. These parts maintain identical pinouts and functionality but offer different Integral Nonlinearity (INL) specifications. Verify that the selected replacement meets the required linearity performance for the specific application.
