MAX1444EHJ+

Analog To Digital Converters (ADC) Overview

The MAX1444EHJ+ is a 10-bit, 40Msps analog-to-digital converter (ADC) featuring a pipelined architecture with fully differential wideband track-and-hold input and digital error correction. It operates from a single 2.7V to 3.6V supply, consuming 57mW while delivering a 59.5dB signal-to-noise ratio at a 20MHz input frequency. The device includes an internal 2.048V precision bandgap reference and supports flexible reference structures for increased accuracy. It features parallel, offset binary, CMOS-compatible three-state outputs operable from 1.7V to 3.6V. The component is housed in a 5x5mm 32-pin TQFP package and is specified over the extended industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead-free status and RoHS compliance. Confirm the package type matches the required 32-pin TQFP footprint. Ensure the temperature grade aligns with the extended industrial specification. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current availability status before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed conversion with low power consumption. Consider the 400MHz input bandwidth and 59.5dB SNR for imaging and communications. Evaluate the need for differential versus single-ended inputs based on system noise requirements. Verify that the 5.5 clock-cycle latency fits within the system timing constraints. Check compatibility with available clock sources regarding jitter specifications.

Analog To Digital Converters (ADC) Part Context

The MAX1444 belongs to a family of high-speed, low-power analog-to-digital converters designed for demanding signal processing tasks. Higher speed, pin-compatible versions such as the MAX1446 (60Msps) and MAX1448 (80Msps) are available within the same series. This specific variant offers a balance of performance and power efficiency suitable for portable and battery-operated equipment where board space is limited.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX1446 and MAX1448. These variants offer higher sampling rates but may require adjustments to clocking and power supply decoupling strategies. Verify that the increased speed does not exceed the system's thermal or power budget constraints.
