PRODUCT DESCRIPTIONThe AD548 is a low power, precision monolithic operational
amplifier. It offers both low bias current (10 pA max, warmed
up) and low quiescent current (200 µA max) and is fabricated
with ion-implanted FET and laser wafer trimming technologies.
Input bias current is guaranteed over the AD548’s entire
common-mode voltage range.
The economical J grade has a maximum guaranteed input offset
voltage of less than 2 mV and an input offset voltage drift of less
than 20 µV/°C. This level of dc precision is achieved utilizing
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.
The AD548 is recommended for any dual supply op amp applica-
tion requiring low power and excellent dc and ac performance.
In applications such as battery-powered, precision instrument
front ends and CMOS DAC buffers, the AD548’s excellent com-
bination 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.
The AD548 is pinned out in a standard op amp configuration
and is available in three performance grades. The AD548J and
AD548K are rated over the commercial temperature range of
0°C to 70°C. The AD548B is rated over the industrial tempera-
ture range of –40°C to +85°C.
The AD548 is available in an 8-lead plastic mini-DIP and
surface-mount (SOIC) packages.
PRODUCT HIGHLIGHTSA combination of low supply current, excellent dc and ac
performance and low drift makes the AD548 the ideal op
amp for high performance, low power applications.The AD548 is pin compatible with industry standard op
amps such as the LF441, TL061, and AD542, enabling
designers to improve performance while achieving a reduction
in power dissipation of up to 85%.Guaranteed low input offset voltage (2 mV max) and drift
(20 µV/°C max) for the AD548J are achieved utilizing
Analog Devices’ laser drift trimming technology, eliminating
the need for external trimming.Analog Devices specifies each device in the warmed-up
condition, insuring that the device will meet its published
specifications in actual use.A dual version, the AD648, is also available.Enhanced replacement for LF441 and TL061.

NOTES
1Input Offset Voltage specifications are guaranteed after five minutes of operation at TA = 25°C.
2Bias Current specifications are guaranteed maximum at either input after five minutes of operation at TA = 25°C. For higher temperature, the current doubles every 10°C.
3Defined as voltages between inputs, such that neither exceeds ±10 V from ground.
4Not recommended for new designs; obsolete April 2002.

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD548 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
