ADS5424MPJYEP

Analog To Digital Converters (ADC) Overview

The ADS5424MPJYEP is a 14-bit, 105-MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates from a 5-V analog supply and provides 3.3-V CMOS-compatible digital outputs. The device features an internal track-and-hold circuit with an input buffer, eliminating the need for external buffering. Key electrical specifications include a differential input range of 2.2 Vpp, a typical signal-to-noise ratio (SNR) of 74 dBc at 105 MSPS, and a spurious-free dynamic range (SFDR) of 93 dBc. Total power dissipation is approximately 1.9 W. The component is housed in a 52-pin PowerPAD thermally-enhanced thin quad flat pack (HTQFP) and supports an extended military temperature range from -55°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'PJYEP' against the manufacturer's datasheet to confirm package type and lead finish specifications. Confirm current production status, as availability may vary. Ensure that the thermal management design accounts for the PowerPAD exposed heatsink requirements specified in the datasheet to maintain junction temperatures within limits during operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed 14-bit ADC with a 5-V analog supply and 3.3-V digital interface is required. The internal reference and buffer simplify system design by reducing external component count. Verify that the 2.2 Vpp differential input range matches the source signal amplitude. Consider the 1.9 W power dissipation and ensure adequate PCB thermal vias are utilized for heat removal through the bottom heatslug.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS5424-EP family, which is characterized by enhanced diminishing manufacturing sources (DMS) support and controlled baseline production. The EP designation indicates qualification in accordance with JEDEC and industry standards, including highly accelerated stress tests (HAST) and temperature cycling, ensuring reliability over the extended temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5424MPJYEP is pin-compatible with the AD6644 and AD6645. When substituting these parts, verify that the alternative device meets the specific SNR, SFDR, and power supply voltage requirements of the original design.
