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.
