FEATURES  
DESCRIPTIO  
220MHz Gain-Bandwidth Product  
The LT®1815/LT1816/LT1817 are low power, high speed,  
very high slew rate operational amplifiers with excellent  
DC performance. The LT1815/LT1816/LT1817 feature  
higher bandwidth and slew rate, much lower input offset  
voltage and lower noise and distortion than other devices  
with comparable supply current. A programmable current  
option (LT1815 and LT1816A) allows power savings and  
flexibility by operating at reduced supply current and  
speed. The circuit topology is a voltage feedback amplifier  
with the slewing characteristics of a current feedback  
amplifier.

Unity-Gain Stable  
1.5mV Maximum Input Offset Voltage  
8µA Maximum Input Bias Current  
800nA Maximum Input Offset Current  
50mA Minimum Output Current, VOUT = ±3V  
±3.5V Minimum Input CMR, VS = ±5V  
Specified at ±5V, Single 5V Supplies  
Operating Temperature Range: 40°C to 85°C  
U
The output drives a 100load to ±3.8V with ±5V sup-  
plies. On a single 5V supply, the output swings from 1V  
to 4V with a 100load connected to 2.5V. Harmonic  
distortion is –70dB for a 5MHz, 2VP-P output driving a  
100load in a gain of –1.  
APPLICATIO S  
The LT1815/LT1816/LT1817 are manufactured on Linear  
Technology’sadvancedlowvoltagecomplementarybipo-  
lar process and are available in a variety of SOT-23, SO,  
MSOP, SSOP and leadless DFN packages.
