MAX1283BEUE+

Analog To Digital Converters (ADC) Overview

The MAX1283BEUE+ is a single-supply, serial 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +2.7V to +3.6V supply and achieves a sampling rate of 300ksps. The device integrates a 4-channel analog-input multiplexer, a high-bandwidth track/hold circuit, and an internal +2.5V reference with a buffer amplifier offering a ±1.5% voltage-adjustment range. It features a 4-wire serial interface compatible with SPI/QSPI/MICROWIRE standards and supports software-configurable unipolar or bipolar input modes within a 16-pin TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 4-channel analog-input multiplexer and high-bandwidth track/hold circuitry for efficient signal acquisition.
• Includes an internal +2.5V reference with a buffer amplifier that allows for external voltage adjustment.
• Features a flexible 4-wire serial interface directly compatible with standard microprocessor protocols without external logic.
• Provides multiple power management modes including normal operation, reduced power, fast power-down, and full power-down.

Analog To Digital Converters (ADC) Applications

• Portable data logging systems
• Battery-powered instruments
• Medical instruments
• Process control applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BEUE confirms the -40°C to +85°C industrial temperature range and TSSOP-16 package. Confirm RoHS compliance status as indicated by the '+' designation in the part number. Ensure the source documentation matches the official Maxim Integrated datasheet for electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1283 variant specifically for low-voltage applications requiring a +2.7V to +3.6V supply. Choose this model over the MAX1282 if lower power consumption at reduced voltages is required. Verify that the 300ksps sampling rate meets the system bandwidth requirements and that the 12-bit resolution is sufficient for the application's accuracy needs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1282/MAX1283 family of serial ADCs. The MAX1283 is the low-voltage counterpart to the MAX1282, which operates at +4.5V to +5.5V. Both share identical pinouts and functional architectures but differ in supply voltage specifications and maximum sampling rates.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1282BEUE+ serves as a direct hardware-compatible alternative if the system supply voltage supports +4.5V to +5.5V operation. Note that the MAX1282 offers a higher sampling rate of 400ksps compared to the MAX1283's 300ksps.
