Product details

12-bit SAR ADC with 500k SPS — signal-chain fit

The MAX11135ATI+ is a 12-bit successive-approximation-register (SAR) ADC sampling at 500k samples per second, built around a MUX-S/H-ADC architecture with a 1:1 S/H-to-ADC ratio. It accepts differential, pseudo-differential, or single-ended inputs through a 2- or 4-channel multiplexer, giving the signal-chain designer flexibility to match the sensor or front-end topology without an external mux.

28-TQFN footprint and thermal pad

Surface-mount assembly with tube packaging suits prototype and low-volume builds; the tube protects leads during handling and reflow.

The -40°C to +125°C operating range qualifies it for industrial and automotive-adjacent environments where the ambient temperature exceeds the commercial 85°C ceiling.

Frequently asked questions

What is the input type and how many channels does MAX11135ATI+ support?

The ADC accepts differential, pseudo-differential, or single-ended inputs through a 2- or 4-channel multiplexer. The input configuration is selected per application via the SPI interface.

What package does MAX11135ATI+ come in?

It is supplied in a 28-lead WFQFN exposed-pad package (5x5 mm, supplier device package 28-TQFN) and shipped in tube packaging.
