MAX1087ETA+

Analog To Digital Converters (ADC) Overview

The MAX1087ETA+T is a micropower, serial output 10-bit analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It operates on a single +3V supply and features a successive-approximation architecture with an internal conversion clock. The device supports a maximum sampling rate of 150ksps and includes AutoShutdown functionality to minimize power consumption between conversions. It accepts two-channel single-ended inputs ranging from 0 to VREF and communicates via a high-speed 3-wire SPI/QSPI/MICROWIRE-compatible interface. The component is housed in an 8-pin TDFN package with an exposed pad.

Analog To Digital Converters (ADC) Feature Summary

• Single-supply operation at +2.7V to +3.6V
• 10-bit resolution with 150ksps sampling rate
• AutoShutdown mode reduces current to <0.2µA
• Internal oscillator eliminates external clock requirements

Analog To Digital Converters (ADC) Applications

• Low power data acquisition systems
• Portable temperature monitors
• Flowmeters
• Touch screens

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ETA+T' corresponds to the TDFN-EP package and tape-and-reel shipping format. Confirm RoHS compliance status for lead-free manufacturing. Check for obsolescence or limited availability status as these components may have restricted production runs.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring low voltage operation (+3V). Ensure the input signal range matches the single-ended configuration (0 to VREF). Verify that the source impedance allows for the specified 1.4µs acquisition time or adjust CNVST timing accordingly.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1086–MAX1089 family of 10-bit SAR ADCs. The MAX1087 variant specifically targets +3V single-supply applications, distinguishing it from the MAX1086 which requires a +5V supply. Both share identical pinouts and functional characteristics except for supply voltage constraints.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes within the same family include the MAX1086 (for +5V systems) or other variants like MAX1088/MAX1089 if differential inputs are required instead of single-ended.
