AD1893JNZ

Overview

The AD1893JNZ is a two-channel audio sample rate converter from the SamplePort series by Analog Devices Inc. It operates on a supply voltage of 2.7V to 5.5V and supports serial interfaces for digital audio interfacing applications. The device is housed in a 20-DIP package with a width of 0.300 inches (7.62mm) and is designed for through-hole mounting. It functions within an operating temperature range of -40°C to +70°C.

Feature Summary

• Two-channel audio sample rate conversion capability
• Wide single-supply voltage operation from 2.7V to 5.5V
• Serial interface support for digital audio systems
• 20-pin DIP package suitable for through-hole mounting

Applications

• Digital audio interfacing
• Sample rate conversion in audio processing chains
• Professional audio equipment signal routing

Procurement Notes

Verify the specific ordering suffix JNZ to confirm the 20-DIP bulk packaging and through-hole configuration. Ensure compatibility with existing board layouts requiring a 0.300-inch DIP footprint. Confirm that the serial interface protocol matches the system requirements before procurement.

Selection Notes

Select this component when a two-channel sample rate converter is required for digital audio applications. The wide voltage range allows flexibility in power supply design. The DIP package is suitable for prototyping or legacy board designs requiring through-hole technology rather than surface-mount solutions.

Part Context

This part belongs to the SamplePort series, which focuses on specialized audio functions. The AD1893 variant specifically provides sample rate conversion functionality. It is distinct from other Audio Special Purpose ICs that may offer codec or amplifier functions instead of pure sampling rate adjustment.

Replacement Considerations

Check for direct pin-compatible replacements within the SamplePort series if availability is an issue. Verify that any substitute maintains the same 2.7V-5.5V supply range and 20-DIP package dimensions to ensure mechanical fit.
