MAX1416EWE+

Analog To Digital Converters (ADC) Overview

The MAX1416EWE+T is a low-power, 2-channel, serial-output analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It utilizes a sigma-delta modulator with a digital filter to achieve 16-bit resolution without missing codes. The device features an internal oscillator, an on-chip input buffer, and a programmable gain amplifier (PGA). It operates on a single 5V supply (4.75V to 5.25V) and offers an SPI-/QSPI™-/MICROWIRE®-compatible serial interface. Key specifications include a maximum integral nonlinearity of ±0.0015% FSR, a power-down current of 16µA, and operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EWE+T' against the manufacturer's official documentation to confirm package type, temperature grade, and reel packaging details. Ensure compatibility with existing board layouts and signal integrity requirements before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1416EWE+ when a 5V single-supply architecture is required for 16-bit precision applications. Compare performance metrics such as noise levels and power consumption against the pin-compatible MAX1415 if a 3V supply design is preferred for lower voltage systems.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1415/MAX1416 family of 16-bit, low-power, 2-channel sigma-delta ADCs. These devices serve as direct pin-compatible upgrades for legacy MX7705 and AD7705 parts, facilitating easier migration to modern low-power architectures while maintaining similar form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1415EWE+ is a pin-compatible alternative within the same family, designed for 3V operation instead of 5V. Verify supply voltage requirements and reference voltage configurations when substituting between these variants.

Analog To Digital Converters (ADC) FAQ

What clock frequencies are supported by the MAX1416?

The MAX1416 supports an external clock frequency (fCLKIN) ranging from 400kHz to 2500kHz. It also features an internal oscillator that can operate at 1MHz or 2.4576MHz.

How does the MAX1416 handle calibration?

The device includes built-in self-calibration features, allowing for on-demand offset and gain self-calibration as well as system calibration. User-programmable offset and gain registers are also available.

What is the input configuration for the analog channels?

The MAX1416 features two fully-differential input channels (AIN1+/AIN1- and AIN2+/AIN2-). The inputs can be configured in either buffered or unbuffered modes depending on the application requirements.
