The AD790JR is a precision, fast comparator fabricated using Analog Devices Inc.'s advanced bipolar process. It is designed to deliver high-performance solutions for a wide range of data acquisition and control applications where response time is critical. This comparator boasts a fast propagation delay, typically 45 ns, which makes it an ideal choice for high-speed analog-to-digital converters (ADCs), zero-crossing detectors, and high-speed sampling circuits.

Key Features

• Fast Propagation Delay: Typically 45 ns, which is beneficial for high-speed applications requiring quick response times.
• Precision Operation: Offers a tightly controlled offset voltage, ensuring accurate comparisons of input signals.
• Single or Dual Power Supply: Can operate from a single +5 V supply or dual supplies up to ±15 V, providing flexibility in various circuit configurations.
• Latch Function: Features a latch input that allows the output to be retained at its current state until the latch is released, useful for time-critical decision-making processes.
• Low Input Bias Current: Minimizes errors in high-impedance circuits, making it suitable for precision applications.
• Output Compatibility: The TTL/CMOS compatible output enables easy interfacing with digital logic circuits.
