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.

ADIsimPE Linear and Mixed-Signal Circuit Simulator – Personal Edition

ADIsimPE, which is powered by SIMetrix/SIMPLIS, is a circuit simulation suite optimized for the design and development of analog and mixed signal circuits. SIMetrix mode is ideal for the simulation of general non-switching circuits. It provides full Pspice compatibility for use with industry-standard SPICE models. SIMPLIS (SIMulation Piecewise-Linear System) mode simulates the operation of switching circuits with vastly improved robustness, speed, and accuracy compared to standard SPICE. It is particularly useful for switching power supply, PLLs, and ADC/DAC applications.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
