It has true single-supply capability with an input voltage range extending below ground in single-supply mode. Output voltage swing extends to within 50 mV of each rail for IOUT ≤ 100 μA, providing outstanding output dynamic range. An offset voltage of 800 μV maximum, an offset voltage drift of 2 μV/°C, input bias currents below 25 pA, and low input voltage noise provide dc precision with source impedances up to a Gigaohm. It provides 16 MHz, −3 dB bandwidth, −108 dB THD @ 20 kHz, and a 22 V/μs slew rate with a low supply current of 2.6 mA per amplifier. The AD823 drives up to 500 pF of direct capacitive load as a follower and provides an output current of 15 mA, 0.5 V from the supply rails. This allows the amplifier to handle a wide range of load conditions.

Small Signal Bandwidth, G = +1 This combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile ampli- fier for applications such as A/D drivers, high speed active filters, and other low voltage, high dynamic range systems. The AD823 is available over the industrial temperature range of −40°C to +85°C and is offered in both 8-lead PDIP and 8-lead SOIC packages. |
