PRODUCT DESCRIPTION

–55°C to +125°C and the AD648T* grade is available pro-

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.

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.

PRODUCT HIGHLIGHTS

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.

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. The AD648 is pin compatible with industry standard dual

op amps such as the LF442, TL062, 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 using Analog

Devices’ laser drift trimming technology.

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.

4. Analog Devices specifies each device in the warmed-up

condition, insuring that the device will meet its published

specifications in actual use.

5. Matching characteristics are excellent for all grades. The

input offset voltage matching between amplifiers in the

AD648J is within 2 mV.

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

6. Crosstalk between amplifiers is less than –120 dB at 1 kHz.
