T he AD648S and AD648T are rated over the military tempera-  
ture range of –55°C to +125°C and are available processed to  
MIL-ST D-883B, Rev. C.  
T he 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  
AD648s entire common-mode voltage range.  
T he AD648 is available in an 8-pin plastic mini-DIP, cerdip,  
SOIC, T O-99 metal can, or in chip form.  
P RO D UCT H IGH LIGH TS  
T he economical J grade has a maximum guaranteed offset volt-  
age of less than 2 mV and an offset voltage drift of less than  
20 µV/°C. T he C grade reduces offset voltage to less than  
0.30 mV and offset voltage drift to less than 3 µV/°C. T his level  
of dc precision is achieved utilizing Analog’s laser wafer drift  
trimming process. T he combination of low quiescent current  
and low offset voltage drift minimizes changes in input offset  
voltage due to self-heating effects. Five additional grades are  
offered over the commercial, industrial and military temperature  
ranges.  
1. A combination of low supply current, excellent dc and ac  
performance and low drift makes the AD648 the ideal op  
amp for high performance, low power applications.  
2. T he AD648 is pin compatible with industry standard dual op  
amps such as the LF442, T L062, and AD642, enabling  
designers to improve performance while achieving a reduc-  
tion in power dissipation of up to 85%.  
3. Guaranteed low input offset voltage (2 mV max) and drift  
(20 µV/°C max) for the AD648J are achieved utilizing Analog  
Devices’ laser drift trimming technology.  
T he AD648 is recommended for any dual supply op amp appli-  
cation requiring low power and excellent dc and ac perfor-  
mance. 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 (86 dB, min on the “C” grade) and  
high open-loop gain ensures better than 12-bit linearity in high  
impedance, buffer applications.  
4. Analog Devices specifies each device in the warmed-up con-  
dition, insuring that the device will meet its published specifi-  
cations in actual use.  
5. Matching characteristics are excellent for all grades. T he  
input offset voltage matching between amplifiers in the  
AD648J is within 2 mV, for the C grade matching is within  
0.4 mV.  
6. Crosstalk between amplifiers is less than –120 dB at 1 kHz.  
7. T he AD648 is available in chip form.  
T he AD648 is pinned out in a standard dual op amp configura-  
tion and is available in seven performance grades. T he AD648J  
and AD648K are rated over the commercial temperature range  
of 0°C to +70°C. T he AD648A, AD648B and AD648C are  
rated over the industrial temperature range of –40°C to +85°C.
