MAX1193ETI+T

Analog To Digital Converters (ADC) Overview

The MAX1193ETI+T is an ultra-low-power, dual-channel, 8-bit analog-to-digital converter (ADC) operating at a sampling rate of 45Msps. It features two fully differential wideband track-and-hold inputs with a 440MHz bandwidth, accepting both differential and single-ended signals. The device delivers a typical signal-to-noise and distortion ratio (SINAD) of 48.5dB at a 5.5MHz input frequency while consuming only 57mW. It operates from a 2.7V to 3.6V analog supply and a separate 1.8V to 3.6V digital supply. The ADC includes an internal 1.024V precision bandgap reference setting a full-scale range of ±0.512V, multiplexed CMOS-compatible tri-state outputs, and three power-down modes. It is housed in a 5mm x 5mm, 28-pin thin QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official documentation. Ensure the ordering suffix matches the required temperature range and packaging format. Confirm that the exposed paddle is properly connected to ground for optimal thermal and electrical performance during installation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed data acquisition is required alongside strict power constraints. Consider the 8-bit resolution and 45Msps sampling rate for applications needing moderate precision at high speeds. Evaluate the need for differential versus single-ended inputs and determine if the internal reference meets accuracy requirements or if an external reference is necessary.

Analog To Digital Converters (ADC) Part Context

The MAX1193 belongs to a family of ultra-low-power dual 8-bit ADCs from Maxim Integrated. Pin-compatible variants include the MAX1191 (7.5Msps) and MAX1192 (22Msps), offering lower speed options. Higher-speed versions such as the MAX1195 through MAX1198 are available for applications requiring faster sampling rates. This component is designed for imaging, instrumentation, and digital communications.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same series include the MAX1191 and MAX1192. For higher sampling frequencies, consider the MAX1195 through MAX1198 models. Verify interface compatibility and power supply requirements when substituting with other ADC families.
