The AD706 is a dual, low power, bipolar op amp that has thelow input bias current of a JFET amplifier, but which offers asignificantly lower IB drift over temperature. It utilizes superbetabipolar input transistors to achieve picoampere input bias currentlevels (similar to FET input amplifiers at room temperature),while its IB typically only increases by 5 at 125°C (unlike aJFET amp, for which IB doubles every 10°C for a 1000×increase at 125°C). The AD706 also achieves the microvoltoffset voltage and low noise characteristics of a precision bipolarinput amplifier.Since it has < 200 pA of bias current, the AD706 does notrequire the commonly used “balancing” resistor. Furthermore,the current noise is only 50 fA/√Hz, which makes this amplifierusable with very high source impedances. At 600 A max supplycurrent (per amplifier), the AD706 is well suited for today’shigh density boards.The AD706 is an excellent choice for use in low frequencyactive filters in 12-bit and 14-bit data acquisition systems, inprecision instrumentation, and as a high quality integrator. TheAD706 is internally compensated for unity gain and is availablein five performance grades. The AD706J is rated over thecommercial temperature range of 0°C to +70°C. The AD706A israted for the extended industrial temperature range of −40°Cto +85°C.The AD706 is offered in two varieties of an 8-lead package:PDIP and surface-mount (SOIC).PRODUCT HIGHLIGHTS The AD706 is a dual low drift op amp that offers JFET level input bias currents, yet has the low IB drift of a bipolar amplifier. It may be used in circuits using dual op amps such as the LT1024. The AD706 provides both low drift and high dc precision. The AD706 can be used in
