C. lithic operational amplifiers. It offers both low bias current The AD648 is available in an 8-lead plastic mini-DIP, (10 pA max, warmed up) and low quiescent current (400 µA CERDIP, and SOIC. max) and is fabricated with ion-implanted FET and laser wafertrimming technologies. Input bias current is guaranteed over the *Not for new design, obsolete April 2002. AD648 s entire common-mode voltage range. PRODUCT HIGHLIGHTS The economical J grade has a maximum guaranteed offset 1. A combination of low supply current, excellent dc and ac voltage of less than 2 mV and an offset voltage drift of less than performance and low drift makes the AD648 the ideal op 20 µV/°C. This level of dc precision is achieved using Analog s amp for high performance, low power applications. laser wafer drift trimming process. The combination of lowquiescent current and low offset voltage drift minimizes changes 2. The AD648 is pin compatible with industry standard dual in input offset voltage due to self-heating effects. Five grades are op amps such as the LF442, TL062, and AD642, enabling offered over the commercial, industrial and military temperature designers to improve performance while achieving a reduc- ranges. tion in power dissipation of up to 85%. The AD648 is recommended for any dual supply op amp 3. Guaranteed low input offset voltage (2 mV max) and drift application requiring low power and excellent dc and ac per- (20 µV/°C max) for the AD648J are achieved using Analog formance.
