MAX1446GHJ+

Analog To Digital Converters (ADC) Overview

The MAX1446GHJ+ is a 10-bit, 60Msps analog-to-digital converter (ADC) featuring a fully differential input and a pipelined architecture with digital error correction. It operates from a single 2.7V to 3.6V supply, consuming 90mW at normal operation and 5µA in shutdown mode. The device includes an internal 2.048V precision bandgap reference and supports parallel, offset binary, three-state outputs compatible with 1.7V to 3.3V logic. It is housed in a 32-pin TQFP package and specified for the extended industrial temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix GHJ+ indicates the automotive-grade temperature range (-40°C to +105°C), distinct from the EHJ+ variant. Confirm RoHS compliance status as indicated by the plus sign. Ensure the source documentation explicitly lists this part number within the ordering information table before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1446GHJ+ when high-speed conversion at 60Msps is required alongside low power consumption. This component is suitable for applications demanding excellent dynamic performance, such as imaging systems. Consider the pin-compatible MAX1444, MAX1448, and MAX1449 if different sampling rates are needed while maintaining the same package footprint.

Analog To Digital Converters (ADC) Part Context

The MAX1446GHJ+ belongs to the MAX1446 family of low-power, high-speed ADCs manufactured by Analog Devices Inc./Maxim Integrated. It shares architectural similarities with the MAX1444, MAX1448, and MAX1449, which offer varying sampling speeds but maintain pin compatibility. The GHJ+ designation specifically denotes the extended industrial temperature capability compared to standard commercial variants.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX1444 (40Msps), MAX1448 (80Msps), and MAX1449 (105Msps). Verify that the specific sampling rate requirements of the application align with these alternative devices before substitution.
