Overview
The AD8564ARZ-REEL7 is a quad comparator from Analog Devices, housed in a 16-lead narrow body SOIC package. It features separate analog and digital power supplies to minimize supply pin interaction. The device operates on a single 5 V supply or dual ±5 V supplies. Key electrical specifications include a typical propagation delay of 7 ns, an input offset voltage of 2.3 mV, and an input bias current of ±4 μA. It provides CMOS/TTL-compatible outputs with a maximum output current of 40 mA per channel.
Feature Summary
- Features separate analog and digital supply sections for independent operation and protection against supply pin interaction.
- Delivers fast 7 ns propagation delay suitable for high-speed timing and data communications circuits.
- Provides wide output swing with TTL/CMOS logic-compatible outputs.
Applications
- High speed timing circuits
- Line receivers
- Data communications systems
- Battery operated instrumentation
Procurement Notes
Verify the specific suffix REEL7 indicates tape and reel packaging configuration. Confirm RoHS compliance status via the manufacturer's ordering guide. Ensure the narrow body SOIC (R-16) package dimensions match the target PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when independent analog and digital supplies are required to isolate noise. Consider the 7 ns propagation delay for high-speed applications. Verify that the 40 mA output drive capability meets load requirements. Check if the industrial temperature range (-40°C to +125°C) aligns with environmental conditions.
Part Context
This part belongs to the AD8564 family of quad comparators. It is designed as a drop-in replacement for MAX901 designs while offering lower supply currents. The device is available in TSSOP, SOIC, and PDIP packages, providing flexibility for various board layout constraints.
Replacement Considerations
The datasheet explicitly identifies the AD8564 as a pin-compatible upgrade for MAX901 designs. Designers replacing MAX901 units should verify that the lower supply current and specific input/output characteristics meet the original circuit requirements.
