MAX1446EHJ+T

Analog To Digital Converters (ADC) Overview

The MAX1446EHJ+T 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 full speed while delivering a 59.5dB signal-to-noise ratio (SNR) at a 20MHz input frequency. The device includes an internal 2.048V precision bandgap reference and supports flexible external reference configurations. It offers a 400MHz -3dB input bandwidth and features a 5µA power-down mode for idle periods. Digital outputs are three-state and CMOS-compatible, operating from 1.7V to 3.3V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' against official documentation, as standard listings often denote the non-tape variant. Confirm lead-free/RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the package type matches the required 32-pin TQFP form factor for your design. Check for any recent product change notices regarding availability or specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic performance and low power consumption are critical for imaging or communications systems. Consider the pin-compatible MAX1444, MAX1448, and MAX1449 if different sampling rates are required. Ensure the system clock meets jitter specifications to maintain optimal SNR. Verify that the digital interface voltage levels align with the target logic family.

Analog To Digital Converters (ADC) Part Context

The MAX1446 belongs to a family of low-power, high-speed ADCs optimized for imaging applications. It shares architectural similarities with the MAX1444, MAX1448, and MAX1449, which offer varying sampling speeds but maintain pin compatibility. This series is designed to provide excellent dynamic performance in a compact 32-pin TQFP package suitable for space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX1444 (40Msps), MAX1448 (80Msps), and MAX1449 (105Msps). These variants share the same package and pinout but differ in maximum sampling rates. Evaluate whether the specific speed requirements of your application necessitate a faster or slower version within this family.
