PRODUCT DESCRIPTION

TRIM  
OS  
The 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.

PRODUCT HIGHLIGHTS  
1. A 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 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.  
2. 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%.  
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.  
3. 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.  
4. Analog Devices specifies each device in the warmed-up  
condition, insuring that the device will meet its published  
specifications in actual use.  
5. A dual version, the AD648, is also available.  
6. Enhanced replacement for LF441 and TL061.  
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.
