DESCRIPTION TSH7x serie offers Single, Dual, Triple and Quad operational amplifiers featuring high video performances with large bandwidth, low distortion and excellent supply voltage rejection. Running at single supply voltage from 3V to 12V, amplifiers feature large output voltage swing and high output current capability to drive standard 150 loads. Low operating voltage makes TSH7x amplifiers ideal for use on portable equipments. The TSH71, TSH73 and TSH75 also feature some Standby input, each of which allows the op amp to be put into a standby mode with low power consumption and high output impedance.The function allows power saving or signals switching/multiplexing for high speed applications and video applications. For board space and weight saving, TSH7x series is proposed in SOT23-5, TSSOP and SO packages. APPLICATION

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; then the amplifier load will be only resistive 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 application, attention should be paid not to use large feedback resistance (>1k) to reduce time constant with 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 the closest to the output pin to minimize its influence. CCIR330 video line Maximum input level: The input level must not exceed the following values:
u negative peak: must be greater than
-Vcc+400mV. u positive peak value: must be lower than +Vcc-400mV. The electrical characteristics show the influence of the load on this parameter. 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 colour 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, colour saturation is not correctly reproduced. The input generator is the Rohde & Schwarz CCVS. The output measurement is done by the Rohde and Schwarz VSA. Measurement on Rohde and Schwarz VSA.

Precautions on asymmetrical supply operation: The TSH7X can be used either with 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 not to introduce an offset mismatch at the amplifier inputs.
R2, R3 are such that the current through them must be superior to 100 times the bias current. So, we take R2=R3=4.7K. Cin, as Cout are chosen to filter the DC signal by the lowpass filters (R1,Cin) and (Rout, Cout). By taking R1=10K, RL=150, and Cin=2uF, Cout=220uF we provide a cutoff frequency below 10Hz. Use of the TSH7X in gain=-1 configuration:

R1=10K will be convenient. C1, C2, C3 are bypass capacitors from perturbation on Vcc as well as for the input and output signals. We choose C1=100nF and C2=C3=100uF.

Some precautions have to be added, specially for low power supply application. A feedback capacitance Cf should be added for better stability. The table summarizes the impact of the capacitance Cf on the phase margin of the circuit.

This example shows a possible application of the TSH7X circuit. Here, you can multiplex the channels for the different standard PAL, NTSC as you filter for the different bands; the video signal can be filtered with two different cutoff frequencies, corresponding to a PAL encoded signal (LPF1) or a NTSC signal (LPF2). You can multiplex input signals, as the outputs are in high impedance state in standby mode.This enables you, to use a PAL filter as the Standby mode is active and to use the NTSC filter otherwise. The video application requires 1Vpeak at input and output. Calculation of components: A decoupling capacitor is provided to cutoff the frequencies below 10Hz according I bias.Hence Ce=10uF, with Rb1=10K. At the output, Cout=220uF. The AOP1 is in 6dB configuration for the adaptation bridge. R1=R2=1K.V1=2Vpk. V2=1Vpk For the PAL communication, we need a lowpass filtering. The load resistance R4 is function of the output resistance of the filter.V3=V2/A1 where A1 is the attenuation factor of the filter LPF1. To compensate the filter insertion loss, we add an additional factor to the gain of the 2nd amplifier AOP2. For example, for an attenuation of 3dB, we choose R5=300 and R6=1K. We have V4=2Vpk and Vout=1Vpk. The calculation of the parameters R7, C7, R8, C8, R9, R10 will be exactly the same .
