Hot-selling and scarce AD820ANZ Low Power FET Input Op Amp 8DIP spot stock

Product Descriptions

The AD820 is a precision, low power FET input op amp thatcan operate from a single supply of 5 V to 36 V,or dual suppliesof ±2.5 V to ±18 V. It has true single-supply capability, with aninput voltage range extending below the negative rail, allowingthe AD820 to accommodate input signals below ground in thesingle-supply mode. Output voltage swing extends to within

10 mV of each rail,providing the maximum output dynamic range .

Offset voltage of 800 μV maximum, offset voltage drift of 2 μV/°C, typical input bias currents below 25 pA, and low inputvoltage noise provide dc precision with source impedances upto 1 GΩ. 1.8 MHz unity gain bandwidth, −93 dB THD at 10 kHz, and 3 V/μs slew rate are provided for a low supplycurrent of 800 μA. The AD820 drives up to 350 pF of directcapacitive load and provides a minimum output current of 15 mA . This allows the amplifier to handle a wide range of loadconditions. This combination of ac and dc performance, plusthe outstanding load drive capability, results in an exceptionallyversatile amplifier for the single-supply user.

The AD820 is available in two performance grades . The A andB grades are rated over the industrial temperature range of−40°C to +85°C. The AD820 is offered in three 8-lead packageoptions:plastic DIP (PDIP),surface mount (SOIC)and (MSOP).
