MAX1301BEUP+T

Analog To Digital Converters (ADC) Overview

The MAX1301BEUP+T is a 16-bit successive-approximation analog-to-digital converter (ADC) in a 20-pin TSSOP package. It features four single-ended or two differential analog input channels with software-programmable ranges. The device operates from a single +5V supply and achieves throughput rates up to 115ksps. A separate digital supply supports interfacing with 2.7V to 5.25V systems via an SPI-compatible serial interface. It includes an internal +4.096V reference, accepts external references between 3.800V and 4.136V, and offers ±16.5V overvoltage tolerant inputs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official documentation. Confirm the specific suffix 'T' indicates tape-and-reel packaging as per standard ordering guidelines. Ensure the operating temperature range matches the application requirements before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four single-ended or two differential channels are required. Verify that the system requires a 16-bit resolution with a maximum sample rate of 115ksps. Ensure the design accommodates the separate analog and digital power supplies and the specific voltage levels for the digital I/O interface.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1300/MAX1301 family of multirange, low-power, 16-bit ADCs. While the MAX1300 variant provides eight single-ended or four differential channels in a 24-pin package, the MAX1301 specifically offers four single-ended or two differential channels in a compact 20-pin TSSOP form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers include MAX1301AEUP+ and MAX1301BEUP+. These variants share identical pinouts and functional specifications within the same series.

Analog To Digital Converters (ADC) FAQ

What is the maximum allowable differential input voltage?

The maximum allowable differential input voltage spans from -6 x VREF to +6 x VREF.

How does the device handle fault conditions on idle channels?

A fault condition on an idle channel does not affect the conversion result of other channels due to the ±16.5V overvoltage tolerance.

What is the function of the REFCAP pin?

For internal reference operation, REFCAP is bypassed with a capacitor to AGND1. For external reference operation, it is connected to AVDD.
