Overview
The AD790JRZ-REEL7 is a fast, precision voltage comparator manufactured by Analog Devices Inc. in an 8-lead SOIC package. It supports single 5 V or dual ±15 V supply operation with a maximum propagation delay of 45 ns and input offset voltage of 250 µV. The device features CMOS/TTL compatible outputs, onboard latch functionality, and operates within the commercial temperature range of 0°C to 70°C.
Feature Summary
- Built-in hysteresis and low-glitch output stage minimize unwanted oscillations
- Onboard latch function enables synchronous operation for data acquisition
- Handles large differential input voltages up to 15 V across input terminals
- Inputs may be referred to ground when operating in single-supply mode
Applications
- Zero-Crossing Detectors
- Overvoltage Detectors
- Pulse-Width Modulators
- Precision Rectifiers
- Discrete A/D Converters
Procurement Notes
Verify that the ordering suffix REEL7 corresponds to the tape and reel packaging format compliant with EIA-481A standards. Confirm the J grade designation indicates the commercial temperature rating of 0°C to 70°C. Ensure the SOIC-8 package matches the required PCB footprint and soldering profile specifications.
Selection Notes
Select this component for applications requiring high-speed response combined with precise voltage threshold detection. The integrated latch simplifies circuit design for synchronous systems. Consider the low power dissipation relative to speed compared to standard comparators. Verify compatibility with available single or dual supply rails during system architecture planning.
Part Context
This part belongs to the AD790 family of high-speed precision comparators fabricated using Analog Devices' Complementary Bipolar process. The series offers various performance grades including industrial and military temperature ranges. The JRZ variant specifically denotes the plastic surface-mount package option within the broader product line.
