Description
The TSH7x series offers single, dual, triple and quad operational amplifiers featuring high video performances with large bandwidth, low distortion and excellent supply voltage rejection. Running with a single supply voltage from 3V to 12V, these amplifiers feature a large output voltage swing and high output current capable of driving standard 150 loads. A low operating voltage makes TSH7x amplifiers ideal for use in portable equipment. The TSH71, TSH73 and TSH75 also feature standby inputs, each of which allows the op-amp to be put into a standby mode with low power consumption and high output impedance. This function allows power saving or signal switching/multiplexing for high-speed applications and video applications. To economize both board space and weight, the TSH7x series is proposed in SOT23-5, TSSOP and SO packages.

Testing Conditions
Layout precautions
To use the TSH7X circuits in the best manner at high frequencies, some precautions have to be taken for power supplies: First of all, the implementation of a proper ground plane in both sides of the PCB is mandatory for high speed circuit applications to provide low inductance and low resistance common return. Power supply bypass capacitors (4.7uF and ceramic 100pF) should be placed as close as possible to the IC pins in order to improve high frequency bypassing and reduce harmonic distortion. The power supply capacitors must be incorporated for both the negative and the positive pins.
Proper termination of all inputs and outputs must be in accordance with output termination resistors; in this way, the amplifier load will be resistive only, and the stability of the amplifier will be improved. All leads must be wide and as short as possible (especially for op-amp inputs and outputs) in order to decrease parasitic capacitance and inductance. For lower gain applications, care should be taken to avoid large feedback resistance (>1k) in order to reduce the time constant of parasitic capacitances. Choose component sizes as small as possible (SMD). Finally, on output, the load capacitance must be negligible to maintain good stability. You can put a serial resistance as close as possible to the output pin to minimize capacitance.
5.2
Maximum input level
Figure 47. CCIR330 video line
The input level must not exceed the following values:
negative peak: must be greater than -VCC+400mV. positive peak value: must be lower than +VCC-400mV.

The electrical characteristics show the influence of the load on this parameter.
5.3
Video capabilities
To characterize the differential phase and differential gain, a CCIR330 video line is used. The video line contains 5 (flat) levels of luma on which is superimposed chroma signal. The first level contains no luma. The luma gives various amplitudes which define the saturation of the signal. The chrominance gives various phases which define the color of the signal. Differential phase (respectively differential gain) distortion is present if a signal chrominance phase (gain) is affected by luminance level. They represent the ability to uniformly process the high frequency information at all luminance levels. When differential gain is present, color saturation is not correctly reproduced. The input generator is the Rohde & Schwarz CCVS. The output measurement was done by the Rohde and Schwarz VSA.

Precautions when operating on an asymmetrical supply
The TSH7X can be used with either a dual or a single supply. If a single supply is used, the inputs are biased to the mid-supply voltage (+VCC/2). This bias network must be carefully designed, in order to reject any noise present on the supply rail. As the bias current is 15uA, you must carefully choose the resistance R1 so as not to introduce an offset mismatch at the amplifier inputs.

RL
R1 = 10K is a typical and convenient value. C1, C2, C3 are bypass capacitors that filter perturbations on VCC, as well as for the input and output signals. We choose C1 = 100nF and C2 = C3 = 100uF. R2, R3 are such that the current through them must be greater than 100 times the bias current. Therefore, we set R2 = R3 = 4.7K.
23/33
Testing Conditions
TSH70,71,72,73,74,75
Cin, as Cout, is chosen to filter the DC signal by the low-pass filters (R1,Cin and Rout, Cout). By taking R1 = 10K, RL = 150, and Cin = 2uF, Cout=220uF we provide a cut-off frequency below 10Hz.

Some precautions must be taken, especially for low-power supply applications. A feedback capacitance, Cf, should be added for better stability. Table 8 summarizes the impact of the capacitance Cf on the phase margin of the circuit.
