AD8170ANZ

Specialized Overview

The AD8170ANZ is a high-speed buffered multiplexer integrating a 2:1 analog switch with a current feedback output amplifier. It provides a 250 MHz bandwidth and a slew rate exceeding 1000 V/µs, settling to 0.1% within 15 ns. The device delivers 50 mA of output drive current and operates on dual supplies ranging from ±4 V to ±6 V, consuming less than 10 mA. It features excellent video specifications including 0.02% differential gain error and 0.05° phase error at 3.58 MHz. The component is housed in an 8-lead Plastic Dual In-Line Package (PDIP) and supports an operating temperature range of -40°C to +85°C.

Specialized Feature Summary

• Integrates fully buffered inputs and outputs with fast channel switching capabilities.
• Features an internal current feedback amplifier with flexible gain setting via external resistors.
• Provides high output drive capability suitable for driving standard video loads.

Specialized Applications

• Pixel switching for Picture-in-Picture LCD and Plasma displays
• High-speed video routers

Specialized Procurement Notes

Verify the package option matches the required footprint, as the AD8170 series includes both PDIP and SOIC variants. Confirm that the specific suffix corresponds to the desired lead form and thermal rating. Ensure the ordering code aligns with the manufacturer's current production status to avoid obsolete stock issues.

Specialized Selection Notes

Select this component when a 2:1 multiplexing function with integrated amplification is required. The AD8170 is distinct from the AD8174, which offers four channels and additional shutdown logic. Designers must account for external feedback resistors to set the closed-loop gain and optimize frequency response stability.

Specialized Part Context

The AD8170 belongs to a family of very high-speed buffered multiplexers designed for demanding signal routing applications. It serves as the two-channel counterpart to the AD8174, offering identical core amplifier performance but without the multi-channel addressing or power-down features found in the 14-pin version.

Specialized Replacement Considerations

The AD8174ANZ is a functional substitute if four channels are acceptable and the circuit can accommodate the additional control pins. Direct pin-to-pin replacement is not possible due to the difference between the 8-lead and 14-lead packages.
