Product Details The OP470 is a high-performance monolithic quad operational amplifier with exceptionally low voltage noise, 5nV/(root)Hz at 1kHz Max, offering comparable performance to PMI"s industry standard OP27. The OP470 features an input offset voltage below 0.4mV, excellent for a quad op amp, and an offset drift under 2µV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP470 is over 1,000,000 into a 10k Ohm load insuring excellent gain accuracy and linearity, even in high-gain applications. Input bias is under 25nA which reduces errors due to signal source resistance. The OP470"s CMR of over 110dB and PSRR of less than 1.8µV/V significantly reduce errors due to ground noise and power supply fluctuations. Power consumption of the quad OP470 is half that of four OP27s, a significant advantage for power conscious applications. The OP470 is unity-gain stable with a gain-bandwidth product of 6MHz and a slew rate of 2V/µs. The OP470 offers excellent amplifier matching which is important for applications such as multiple gain blocks, low-noise instrumentation amplifiers, quad buffers, and low-noise active filters. The OP470 conforms to the industry standard 14-pin DIP pinout. It is pin compatible with the OP11, LM 148/149, HA4741, HA5104, and RM4156 quad op amps and can be used to upgrade systems using these devices. For higher speed applications the OP471, with a slew rate of 8V/µs, is recommended. ### Features and Benefits
description/ordering information The LM148, LM248, and LM348 are quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the µA741. These amplifiers exhibit low supply-current drain and input bias and offset currents that are much less than those of the µA741. • µA741 Operating Characteristics • Low Supply-Current Drain . . . 0.6 mA Typ (per amplifier) • Low Input Offset Voltage • Low Input Offset Current • Class AB Output Stage • Input/Output Overload Protection • Designed to Be Interchangeable With Industry Standard LM148, LM248, and LM348
