Features  
General Description  
The KH231 Buffer/Amplifier is a wideband operational  
amplifier designed specifically for high-speed, low-  
gain applications. The KH231 is based on a current  
feedback op amp topology-a unique design that both  
eliminates the gain-bandwidth tradeoff and permits  
unprecedented high-speed performance. (See table below.)  
I
165MHz closed-loop – -3dB bandwidth  
I
15ns settling to 0.05%  
I
1mV input offset voltage, 10µV/°C drift  
I
100mA output current  
I
Excellent AC and DC linearity  
I
Direct replacement for CLC231  
The KH231 Buffer/Amplifier is the ideal design alter-  
native to low precision open-loop buffers and oscillation-  
prone conventional op amps. The KH231 offers precise  
gains from 1.000 to -5.000 and linearity that is a  
true 0.1%-even for demanding 50Ω loads. Open-loop  
buffers, on the other hand, offer a nominal gain of  
0.95 0.03 and a linearity of only 3% for typical loads.  
A buffer’s settling time may look impressive but it is  
usually specified at unrealistically large load resis-  
tances or when the effects of thermal tail are not  
included; the KH231 Buffer/Amplifier settles to 0.05%  
in 15ns-while driving a 100Ω load.  
Applications  
I
Driving flash A/D converters  
I
Precision line driving  
(a gain of 2 cancels matched-line losses)  
I
DAC current-to-voltage conversion  
Low-power, high-speed applications (50mW @ 5V)  
I
Small Signal Pulse Response  
Av = 2  
Offsets and drifts, usually a low priority in conven-  
tional high-speed op amp designs, were not ignored  
in the KH231; the input offset voltage is typically 1mV  
and input offset voltage drift is only 10µV/°C. The  
KH231 is stable and oscillation-free across the entire  
gain range and since it’s internally compensated, the  
user is saved the trouble of designing external com-  
pensation networks and having to “tweak” them in  
production. The absence of a gain-bandwidth trade-  
off in the KH231 allows performance to be predicted  
easily; the table below shows how the bandwidth is  
affected very little by changing the gain setting.
