ADS5423MPJYEP

Analog To Digital Converters (ADC) Overview

The ADS5423MPJYEP is a 14-bit, 80-MSPS analog-to-digital converter (ADC) from Texas Instruments. It operates from a 5-V analog supply and provides 3.3-V CMOS-compatible digital outputs. The device features an on-chip input buffer, track-and-hold circuit, and internal reference generator. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 74 dBc at 80 MSPS with a 50-MHz IF input, and a Spurious-Free Dynamic Range (SFDR) of 94 dBc under the same conditions. It supports a differential input range of 2.2 Vpp and functions within an extended temperature range of –55°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized channels due to its enhanced product qualification pedigree. Confirm that the specific MPJYEP suffix corresponds to the tray packaging variant as defined in the ordering information table. Ensure compatibility with existing thermal management designs given the PowerPAD package requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for high-linearity applications requiring 14-bit precision at 80 MSPS. The internal reference simplifies board design by eliminating external voltage references. Ensure the driving circuit can provide the required 2.2 Vpp differential swing and that the system accommodates the 3.3-V logic level for digital outputs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS5423-EP family, which is designed for military and high-reliability environments. It offers pin compatibility with the AD6644/45 devices. The EP designation indicates controlled baseline manufacturing with enhanced diminishing manufacturing sources support and strict qualification testing including HAST and temperature cycling.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5423MPJYEP is pin-compatible with the AD6644 and AD6645. Designers replacing these parts should verify that the replacement meets the specific SNR and SFDR requirements at the target input frequencies, as performance characteristics may vary between manufacturers.
