MAX190BEWG

Analog To Digital Converters (ADC) Overview

The MAX190BEWG is a low-power, 12-bit sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates a track/hold amplifier and an internal reference voltage source. The device operates with a single 5V supply and supports serial data output via an RS-232 compatible interface. Key electrical specifications include a sampling rate of 75ksps and a power-down mode for energy efficiency. The BEWG suffix indicates a specific package configuration, typically a small outline package, suitable for surface-mount applications in compact electronic designs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the exact package type and temperature range associated with the BEWG suffix against the official datasheet before procurement. Confirm availability status as older components may have limited stock or end-of-life implications. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 12-bit accuracy and low power consumption is required for battery-operated devices. Consider the 75ksps speed limit for application bandwidth needs. Verify that the serial interface timing meets the host controller's capabilities. Compare with higher-speed alternatives like the MAX128 series if faster sampling is necessary.

Analog To Digital Converters (ADC) Part Context

The MAX190 belongs to Maxim Integrated's family of low-power, single-supply ADCs. It is designed for applications requiring moderate precision without the complexity of external reference or amplification circuits. The BEWG variant specifies the physical packaging, distinguishing it from other pinout or thermal options within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements should be sought from the MAX190 family or the MAX128 series for higher speed. Verify pin compatibility and software register settings when substituting. Check for updated RoHS compliance status if environmental regulations are a constraint.
