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

AD648’s 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.

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.
