GENERAL DESCRIPTION
The Analog Devices AD741 Series are high performance monolithic operational amplifiers. All the devices feature full short
circuit protection and internal compensation.
The Analog Devices AD741J, AD741K, AD741L, and AD741S
are specially tested and selected versions of the standard AD741
operational amplifier. Improved processing and additional electrical testing guarantee the user precision performance at a very
low cost. The AD741J, K and L substantially increase overall
accuracy over the standard AD741C by providing maximum
limits on offset voltage drift and significantly reducing the errors
due to offset voltage, bias current, offset current, voltage gain,
power supply rejection and common-mode rejection. For example,
the AD741L features maximum offset voltage drift of 5 µV/°C,
offset voltage of 0.5 mV max, offset current of 5 nA max, bias
current of 50 nA max and a CMRR of 90 dB min. The AD741S
offers guaranteed performance over the extended temperature
range of –55°C to +125°C, with max offset voltage drift of
15 µV/°C, max offset voltage of 4 mV, max offset current of
25 nA, and a minimum CMRR of 80 dB.
NC = NO CONNECT
HIGH OUTPUT CAPABILITY
Both the AD741J and AD741S offer the user the additional
advantages of high guaranteed output current and gain at low
values of load impedance. The AD741J guarantees a minimum
gain of 25,000 swinging ± 10 V into a 1 kΩ load from 0°C to
+70°C. The AD741S guarantees a minimum gain of 25,000
swinging ± 10 V into a 1 kΩ load from –55°C to +125°C.
All devices feature full short circuit protection, high gain, high
common-mode range and internal compensation. The AD741J,
K and L are specified for operation from 0 to +70°C and are
available in both the TO-99 and mini-DIP packages. The
AD741S is specified for operation from –55°C to +125°C, and
is available in the TO-99 package.

For supply voltages less than ± 15 V, the absolute maximum input voltage is equal to the supply voltage.
All min and max specifications are guaranteed. Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are
used to calculate outgoing quality levels.
Specifications subject to change without notice.
