Product details

8-bit SAR ADC with flexible input mux

The MAX11142ATI+ is an 8-bit successive-approximation-register (SAR) ADC from Analog Devices, sampling at 500k samples per second over an SPI interface. It accepts differential, pseudo-differential, or single-ended inputs through an internal multiplexer, configurable as four differential or eight single-ended channels.

Input flexibility — differential or single-ended

The mux accepts differential, pseudo-differential, or single-ended signals. Differential mode rejects common-mode noise on twisted-pair runs from remote sensors; single-ended mode doubles the channel count to eight when the signal source is local and ground-referenced.

Frequently asked questions

What is the resolution and number of channels of MAX11142ATI+?

The MAX11142ATI+ is an 8-bit ADC with a configurable input mux that provides either four differential or eight single-ended channels.

Are there any direct equivalents or replacements for MAX11142ATI+?

No direct pin-compatible equivalent is listed in the available records. The MAX11142ATI+ is a current-production part; for a second-source option, review the broader MAX1114x family for similar 8-bit SAR ADCs with SPI and the same package footprint.
