Operational Amplifier  
DESCRIPTION  
FEATURES  
TheLT®1468isaprecisionhighspeedoperationalamplifier  
with 16-bit accuracy and 900ns settling to 150μV for 10V  
signals.ThisuniqueblendofprecisionandACperformance  
makes the LT1468 the optimum choice for high accuracy  
applications such as DAC current-to-voltage conversion  
and ADC buffers. The initial accuracy and drift character-  
istics of the input offset voltage and inverting input bias  
current are tailored for inverting applications.

Minimum DC Gain: 1000V/mV  
n
Minimum Output Swing into 2k: 12.8V  
The 90MHz gain bandwidth ensures high open-loop gain  
at frequency for reducing distortion. In noninverting ap-  
plications such as an ADC buffer, the low distortion and  
DC accuracy allow full 16-bit AC and DC performance.

The 22V/μs slew rate of the LT1468 improves large-signal  
performance in applications such as active filters and  
instrumentation amplifiers compared to other precision  
op amps.  
Specified at 5V and 15V
