MAX1444EHJ+T

Analog To Digital Converters (ADC) Overview

The MAX1444EHJ+T 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 offers a 5µA power-down mode. It features parallel, offset binary, CMOS-compatible three-state outputs and is housed in a 5x5mm 32-pin TQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' against official documentation, as standard listings often indicate tray packaging while '+T' may denote tape and reel. Confirm RoHS compliance status and lead-free certification directly with Analog Devices or authorized distributors. Ensure the component matches the extended industrial temperature range specifications before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption alongside high dynamic performance at moderate sampling rates. Consider the pin-compatible MAX1446 (60Msps) or MAX1448 (80Msps) if higher throughput is required. Evaluate the need for external versus internal reference configurations based on system accuracy requirements.

Analog To Digital Converters (ADC) Part Context

The MAX1444 belongs to a family of low-power, 3V analog-to-digital converters designed for imaging and digital communications. It shares architectural similarities with the MAX1446 and MAX1448, which offer higher sampling speeds but maintain pin compatibility. This series targets applications where power efficiency and compact form factors are critical design constraints.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1446EHJ+ and MAX1448EHJ+ are pin-compatible alternatives offering 60Msps and 80Msps sampling rates respectively. Verify that the increased speed meets system timing requirements without compromising power budgets.
