FEATURES  
DESCRIPTIO  
Offset Voltage: 50µV Max (LT1884A)  
The LT®1884/LT1885 op amps bring high accuracy input  
performance to amplifiers with rail-to-rail output swing  
while providing faster response than other precision am-  
plifiers. Input offset voltage is trimmed to less than 50µV  
and the low drift maintains this accuracy over the operat-  
ing temperature range. Input bias currents are an ultralow  
400pA maximum.  
Input Bias Current: 400pA Max (LT1884A)  
Offset Voltage Drift: 0.8µV/°C Max  
Rail-to-Rail Output Swing  
Operates with Single or Split Supplies  
Open-Loop Voltage Gain: 1 Million Min  
1mA Maximum Supply Current Per Amplifier  
Slew Rate: 1V/µs  
Standard Pinouts  
The amplifiers work on any total power supply voltage  
between 2.7V and 36V (fully specified from 5V to ±15V).  
Output voltage swings to within 40mV of the negative  
supply and 220mV of the positive supply make these  
amplifiers good choices for low voltage single supply  
operation.  
U
APPLICATIO S  
Thermocouple Amplifiers  
Bridge Transducer Conditioners  
Slew rates of 1V/µs with a supply current of less than 1mA  
per amplifier give superior response and settling time  
performance in a low power precision amplifier.  
Instrumentation Amplifiers  
Battery-Powered Systems  
Photo Current Amplifiers  
Precision Integrators  
The dual LT1884 is available with standard pinouts in  
8-pin SO and PDIP packages. The quad LT1885 is also in  
the standard pinout 14-pin SO package.
