FEATURES  
DESCRIPTION  
TheLT®1468-2isaprecisionhighspeedoperationalampli-  
fier with 16-bit accuracy, decompensated to be stable in a  
gain of 2 or greater. The combination of precision and AC  
performance makes the LT1468-2 the optimum choice for  
highaccuracyapplicationssuchasDACcurrent-to-voltage  
conversion and ADC buffers. The initial accuracy and drift  
characteristicsoftheinputoffsetvoltageandinvertinginput  
bias current are tailored for inverting applications.

200MHz Gain Bandwidth Product  
30V/μs Slew Rate  
Settling Time: 800ns (10V Step, 150ꢀV)  
Specified at 5V and 15V Supplies  
Low Distortion, 96.±dB for 100kHz, 105  
Maximum Input Offset 5oltage: 7±μ5  
P-P  
Maximum Input Offset 5oltage Drift: 2μ5/ꢁC  
Maximum (ꢀ) Input Bias Current: 10nA  
Minimum DC Gain: 10005/m5  
The 200MHz 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 high slew rate of the LT1468-2 improves large-signal  
performance in applications such as active filters and  
instrumentation amplifiers compared to other precision  
op amps.  
Minimum Output Swing into 2k: ±12.85  
Input Noise 5oltage: ±n5/√Hz  
Input Noise Current: 0.6pA/√Hz  
Total Input Noise Optimized for 1k < R < 20k  
S
Available in an 8-Lead Plastic SO Package  
and 8-Lead DꢂN Package  
The LT1468-2 is specified on power supply voltages of  
±±5 and ±1±5 and from ꢀ40ꢁC to 8±ꢁC. ꢂor a unity-gain  
stable op amp with same DC performance, see the LT1468  
datasheet.
