AD75019JPZ

Overview

The AD75019JPZ is a 16 × 16 analog crosspoint switch array containing 256 switches in a compact 44-lead PLCC package. It supports wide signal ranges up to supply rails of 24 V or ±12 V with a typical on-resistance of 150 Ω. The device features TTL/CMOS-compatible serial control lines, allowing data loading via SIN and SCLK inputs. A minimum clock rate of 20 kHz and maximum of 5 MHz enable data load times as short as 52 μs. Quiescent power consumption is low at 2 mW. The switches accommodate signals with amplitudes up to the supply rails, and isolation between channels reaches 92 dB at 1 kHz.

Feature Summary

• Contains 256 analog switches arranged in a 16 × 16 array for flexible signal routing.
• Supports wide signal voltage ranges extending to supply rails of 24 V or ±12 V.
• Features serial input interface that simplifies connection to microprocessors and digital logic.
• Includes serial output capability to allow cascading multiple units for expanded channel counts.

Applications

• Signal routing in communication and networking systems
• Audio and video signal switching applications
• Test and measurement equipment requiring multi-channel signal path configuration

Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The AD75019JPZ denotes a RoHS-compliant part in a 44-lead Plastic Leaded Chip Carrier (PLCC) package. Ensure the procurement documentation matches the required temperature range of 0°C to 70°C. Confirm that the source provides the official Analog Devices datasheet for accurate pinout and electrical specifications before integration.

Selection Notes

Select this component when a dense crosspoint switching matrix is required within a limited footprint. The serial interface reduces pin count compared to parallel control schemes. Consider the 150 Ω typical on-resistance and 20 MHz bandwidth for signal integrity requirements. Verify that the system power supplies can meet the BiMOS II process sequencing constraints between analog and digital rails.

Part Context

The AD75019 is fabricated using Analog Devices’ BiMOS II process, which combines CMOS devices for low-distortion switching with bipolar devices for ESD protection. This technology enables high performance in a compact form factor. The device is part of the broader AD75019 series, which includes reel variants for automated assembly. It serves as a foundational building block for complex signal routing architectures.

Replacement Considerations

The AD75019JPZ-REEL is the reel-packaged version of the same functional device. For higher bandwidth requirements, consider the AD8116, which offers 200 MHz operation but requires different interface considerations. No direct pin-for-pin replacements are documented in the provided sources; verify compatibility carefully if substituting.

FAQ

What is the minimum clock rate required for the serial shift register?

The serial shift register is dynamic and requires a minimum clock rate of 20 kHz to prevent data loss.

How is data transferred from the shift register to the switch latches?

Data is transferred by pulsing the Parallel Clock (PCLK) input low after the 256-bit shift register is filled. This must occur within 5 ms of filling the register.

Can multiple AD75019 devices be used together?

Yes, multiple devices can be cascaded. The Serial Output (SOUT) of one device connects directly to the Serial Input (SIN) of the next to extend the number of switches.
