AD648JR Datasheet

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps


The AD648JR is a matched pair of low power, precision monolithicoperational amplifiers. It offers both low bias current(10 pA max, warmed up) and low quiescent current (400 mAmax) and is fabricated with ion-implanted FET and laser wafertrimming technologies. Input bias current is guaranteed over theAD648’s entire common-mode voltage range.The economical J grade has a maximum guaranteed offset voltageof less than 2 mV and an offset voltage drift of less than20 mV/°C. The C grade reduces offset voltage to less than0.30 mV and offset voltage drift to less than 3 mV/°C. This levelof dc precision is achieved utilizing Analog’s laser wafer drifttrimming process. The combination of low quiescent currentand low offset voltage drift minimizes changes in input offsetvoltage due to self-heating effects. Five additional grades areoffered over the commercial, industrial and military temperatureranges.The AD648 is recommended for any dual supply op amp applicationrequiring low power and excellent dc and ac performance.In applications such as battery-powered, precisioninstrument front ends and CMOS DAC buffers, the AD648’sexcellent combination of low input offset voltage and drift, lowbias current and low 1/f noise reduces output errors. Highcommon-mode rejection (86 dB, min on the “C” grade) andhigh open-loop gain ensures better than 12-bit linearity in highimpedance, buffer applications.The AD648 is pinned out in a standard dual op amp configurationand is available in seven performance grades. The AD648Jand AD648K are rated over the commercial temperature rangeof 0°C to +70°C. The AD648A, AD648B and AD648C arerated over the industrial temperature rangeof –40°C to +85°C.The AD648S and AD648T are rated over the military temperaturerange of –55°C to +125°C and are available processed toMIL-STD-883B, Rev. C.The AD648 is available in an 8-pin plastic mini-DIP, cerdip,SOIC, TO-99 metal can, or in chip form.
