  • Description

    The AD844AQ is a high-speed operational amplifier that falls under the Low Noise Amplifiers (LNA) - RF category. It is designed using Analog Devices’ junction isolated complementary bipolar (CB) process, which ensures high bandwidth, very fast large signal response, and excellent dc performance. This monolithic amplifier is primarily optimized for use in current to voltage applications and can function efficiently as an inverting mode amplifier.

    Specifications and features

    • Wide Bandwidth: The AD844AQ is designed with a wide bandwidth of 60 MHz at Gain of –1 and 33 MHz at Gain of –10.
    • Very High Output Slew Rate: This model has an output slew rate of up to 2000 V/μs.
    • 20 MHz Full Power Bandwidth: It is equipped with a 20 MHz full power bandwidth of 20 V p-p, RL = 500 Ω.
    • Fast Settling: It has a fast settling capability of 100 ns to 0.1% (10 V Step).
    • Differential Error: The differential gain error is 0.03% at 4.4 MHz, while Differential Phase Error is 0.158 at 4.4 MHz.
    • High Output Drive: AD844AQ has a high output drive of 650 mA into 50 Ω Load.
    • Low Offset Voltage: It has a low offset voltage of 150 mV Max (B Grade).
    • Low Quiescent Current: This model has a low Quiescent Current of 6.5 mA.

    Application Scenarios

    The AD844AQ can be effectively used in various applications such as Flash ADC Input Amplifiers, High-Speed Current DAC Interfaces, Video Buffers and Cable Drivers, and Pulse Amplifiers.

    Comparison
