Part Description

The AD648 is a matched pair of low power, precision mono- lithic operational amplifiers. It offers both low bias current (10 pA max, warmed up) and low quiescent current (400 µA max) and is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD648’s entire common-mode voltage range. The economical J grade has a maximum guaranteed offset voltage of less than 2 mV and an offset voltage drift of less than 20 µV/°C. This level of dc precision is achieved using Analog’s laser wafer drift trimming process. The combination of low quiescent current and low offset voltage drift minimizes changes in input offset voltage due to self-heating effects. Five grades are offered over the commercial, industrial and military temperature ranges. The AD648 is recommended for any dual supply op amp application requiring low power and excellent dc and ac per- formance. In applications such as battery-powered, precision instrument front ends and CMOS DAC buffers, the AD648’s excellent combination of low input offset voltage and drift, low bias current, and low 1/f noise reduces output errors. High common-mode rejection (82 dB, min on the “B” grade) and high open-loop gain ensures better than 12-bit linearity in high impedance, buffer applications. The AD648 is pinned out in a standard dual op amp configura- tion and is available in seven performance grades. The AD648J and AD648K are rated over the commercial temperature range of 0°C to 70°C. The AD648 and AD648B are rated over the industrial temperature range of –40°C to +85°C. The AD648S and AD648T are rated over the military temperature range of –55°C to +125°C and the AD648T* grade is available pro- cessed to MIL-STD-883B, Rev. C. The AD648 is available in an 8-lead plastic mini-DIP, CERDIP, and SOIC. *Not for new design, obsolete April 2002.
