GENERAL DESCRIPTION
The AD820 is a precision, low power FET input op amp that
can operate from a single supply of 5 V to 36 V, or dual supplies
of ±2.5 V to ±18 V. It has true single-supply capability, with an
input voltage range extending below the negative rail, allowing
the AD820 to accommodate input signals below ground in the
single-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 input
voltage noise provide dc precision with source impedances up
to 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 supply
current of 800 μA. The AD820 drives up to 350 pF of direct
capacitive load and provides a minimum output current of
15 mA. This allows the amplifier to handle a wide range of load
conditions. This combination of ac and dc performance, plus
the outstanding load drive capability, results in an exceptionally
versatile amplifier for the single-supply user.
The AD820 is available in two performance grades. The A and
B grades are rated over the industrial temperature range of
40°C to +85°C. The AD820 is offered in three 8-lead package
options: plastic DIP (PDIP), surface mount (SOIC) and (MSOP).
