MAX1191ETI+T

Analog To Digital Converters (ADC) Overview

The MAX1191ETI+T is a dual-channel, ultra-low-power analog-to-digital converter (ADC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an 8-bit resolution and a sampling rate of 45 Msps, utilizing a pipeline architecture. The device supports both differential and single-ended input configurations with parallel interface connectivity. It operates on a single 2.7 V to 3.6 V supply voltage for both analog and digital domains. Key performance metrics include a signal-to-noise ratio (SNR) of 48.5 dB, integral nonlinearity (INL) of +/- 1 LSB, and differential nonlinearity (DNL) of +/- 1 LSB. The component is housed in a 28-lead TQFN package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ETI+T' to confirm the tape-and-reel packaging and lead-free (RoHS compliant) status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering part number matches the exact package type and temperature grade required for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion at moderate resolution (8-bit) and high speed (45 Msps) is required with strict power constraints. Compare against higher-resolution alternatives if precision is prioritized over speed. Verify that the parallel interface timing requirements align with the host processor capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX119x family of low-power ADCs from Maxim Integrated. It shares architectural similarities with other members like the MAX1192 and MAX1193, differing primarily in channel count and specific pinout configurations. The ETI+T designation indicates a surface-mount TQFN package with reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the MAX1192ETI+T and MAX1193ETI+T, though pinouts and channel counts may differ. Cross-reference datasheets for compatibility before substitution.
