MAX1415AEWE+

Analog To Digital Converters (ADC) Overview

The MAX1415AEWE+ is a low-power, 2-channel, serial-output analog-to-digital converter (ADC) utilizing sigma-delta modulation to achieve 16-bit resolution with no missing codes. It operates on a single supply voltage ranging from 2.7V to 3.6V and features an internal oscillator selectable between 1MHz and 2.4576MHz. The device includes an on-chip input buffer and a programmable gain amplifier (PGA) with settings from 1 to 128. It communicates via an SPI-/QSPI™-/MICROWIRE®-compatible serial interface and is housed in a 16-pin Wide SO package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EWE+' against the manufacturer's current ordering guide to confirm package type and temperature range. Ensure the external clock source matches the selected internal frequency configuration. Confirm RoHS compliance status for the specific manufacturing lot before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution with two differential channels is required for precision measurement applications. Consider the MAX1416 variant if a 5V supply voltage is necessary instead of the 3V range supported by the MAX1415. Evaluate the need for buffered versus unbuffered inputs based on source impedance requirements.
