MAX1192ETI+

Analog To Digital Converters (ADC) Overview

The MAX1192ETI+ is an ultra-low-power, dual-channel, 8-bit analog-to-digital converter (ADC) operating at a sampling rate of 22Msps. It features two fully differential wideband track-and-hold inputs with a 440MHz bandwidth, supporting both differential and single-ended signal configurations. The device delivers a typical Signal-to-Noise and Distortion Ratio (SINAD) of 48.6dB at an input frequency of 5.5MHz while consuming only 27.3mW. It operates from a 2.7V to 3.6V analog supply and a separate 1.8V to 3.6V digital output driver supply. The ADC includes three power-down modes for energy conservation during idle periods.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as the MAX1192 series may be subject to discontinuation notices. Confirm that the specific ordering suffix corresponds to the required tape and reel packaging format. Ensure compatibility with the extended industrial temperature range specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel acquisition at 22Msps is required with minimal power budget constraints. Consider the internal reference option for simplified designs or external references for higher accuracy needs. Evaluate the 28-pin Thin QFN package dimensions against available PCB real estate and thermal dissipation requirements.

Analog To Digital Converters (ADC) Part Context

The MAX1192 belongs to a family of ultra-low-power dual 8-bit ADCs from Maxim Integrated. Pin-compatible alternatives include the MAX1191 for lower sampling rates and the MAX1193 for higher speeds. These devices share similar architectural features but differ in clock frequency specifications and dynamic performance metrics.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible substitutes include the MAX1191 and MAX1193. Verify that the alternative part number meets the specific sampling rate and power consumption requirements of the design.
