Analog Devices Inc. AD823ARZ

The AD823 is a surface mount operational amplifier with a base part number of AD823. It has a peak reflow temperature of 260 degrees Celsius, making it suitable for a wide range of applications. This operational amplifier has 8 terminations, providing flexibility in circuit design. With a gain bandwidth product of 10MHz, it offers high performance and precision. Additionally, its input voltage noise density of 16nV/sqrt Hz ensures low noise operation. Measuring at a length of 5mm, it is compact in size and can easily fit into tight spaces. Although it is not radiation hardened, it is compliant with RoHS3 standards, making it a safe and environmentally friendly choice.
The AD823 is a 16 MHz dual precision JFET input op-amp that may be powered by a single 3.0 V to 36 V supply or two 1.5 V to 18 V supplies. In single-supply mode, it features a real single-supply input voltage range that extends below ground. For IOUT 100 A, the output voltage swing is within 50 mV of each rail, resulting in a wide output dynamic range.
With source impedances up to a Gigaohm, dc precision is provided by an offset voltage of 800V maximum, an offset voltage drift of 2V/°C, input bias currents below 25 pA, and low input voltage noise. With a low supply current of 2.6 mA per amplifier, it provides 16 MHz, 3 dB bandwidth, 108 dB THD @ 20 kHz, and a 22 V/s slew rate. As a follower, the AD823 drives up to 500 pF of direct capacitive load and generates a 15 mA output current at 0.5 V from the supply rails. This enables the amplifier to cope with a variety of load circumstances.
