PRODUCT DE SCRIPT ION
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
μ
A
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 economical J grade has a maximum guaranteed offset volt-
age of less than 2 mV and an offset voltage drift of less than
20
μ
V/
°
C. T he C grade reduces offset voltage to less than
0.30 mV and offset voltage drift to less than 3
μ
V/
°
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.
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.
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.
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 available in an 8-pin plastic mini-DIP, cerdip,
SOIC, T O-99 metal can, or in chip form.
PRODUCT HIGHLIGHT S
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
μ
V/
°
C max) for the AD648J are achieved utilizing Analog
Devices’ laser drift trimming technology.
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.
