1 WIDE BANDWIDTH AND BIPOLAR INPUTS SINGLE OPERATIONAL AMPLIFIER LOW DISTORTION GAIN BANDWIDTH PRODUCT : 150MHz UNITY GAIN STABLE SLEW RATE : 190V/µs VERY FAST SETTLING TIME : 20ns (0.1%) DESCRIPTION The TSH150 is a wideband monolithic operational amplifier, internally compensated for unity-gain stability. Low noise and low distortion, wide bandwidth and high linearity make this amplifier suitable for RF and video applications. Short circuit protection is provided by an internal current-limiting circuit. The TSH150 has internal electrostatic discharge (ESD) protection circuits and fulfills MILSTD883C-Class2.

4 TEST WAVEFORM EVALUATION CIRCUIT +5V 10µF 50Ω V in 50% PRINTED CIRCUIT LAYOUT t s t d t r 90% 10% 0.1% of edge amplitude As for any high frequency device, a few rules must be observed when designing the PCB to get the best performances from this high speed op amp. From the most to the least important points : Each power supply lead has to be bypassed to ground with a 10nF ceramic capacitor very close to the device and a 10µF tantalum capacitor. To provide low inductance and low resistance common return, use a ground plane or common point return for power and signal. All leads must be wide and as short as possible especially for op amp inputs. This is in order to decrease parasitic capacitance and inductance. Use small resistor values to decrease time constant with parasitic capacitance. Choose component sizes as small as possible (SMD). On output, decrease capacitor load so as to avoid circuit stability being degraded which may cause oscillation. You can also add a serial resistor in order to minimise its influence. One can add in parallel with feedback resistor a few pf ceramic capacitor C F adjusted to optimize the settling time. Input 1kΩ -5V 10nF 10nF 10µF 1kΩ C F 50Ω Output 4/6
