Product details

10-bit SAR ADC with flexible input mux

The Maxim MAX1031BEEG+ is a 10-bit successive-approximation-register (SAR) analog-to-digital converter with a sample-and-hold front end, rated for 300k samples per second. It offers a configurable input multiplexer that supports either 8 differential or 16 single-ended channels, selectable through the SPI interface. The onboard temperature sensor feature lets you monitor die temperature without an external thermistor — useful for thermal management in multi-channel data acquisition systems where the ADC sits near warm components.

Package and footprint — 24-QSOP

Housed in a 24-pin QSOP (3.90 mm wide, 0.154" body), the MAX1031BEEG+ uses a fine-pitch surface-mount footprint that saves board area compared to a TSSOP-24. The supplier device package is 24-QSOP; the tube shipping medium is the standard delivery format.

Lifecycle and sourcing

The MAX1031BEEG+ carries an Active product status with ROHS3 compliance.

Frequently asked questions

What is the closest pin-compatible alternative to MAX1031BEEG+?

Within the same Maxim family, the MAX1030 series shares the same pinout and package options. The key difference is resolution: the MAX1031 is 10-bit, while siblings like the MAX1030 offer 12-bit resolution at the same sampling rate. Verify the specific order code against your required bit depth before substituting.

What does the temperature sensor feature on the MAX1031BEEG+ do?

The integrated temperature sensor allows the ADC to measure its own die temperature, which can be read through the SPI interface. This is useful for thermal monitoring in systems where the ADC is near heat-generating components like power stages or processors.
