Description
The TSH8x series offers single, dual and quad operational amplifiers featuring high video performance with large bandwidth, low distortion and excellent supply voltage rejection. These amplifiers also feature large output voltage swings and a high output current capability to drive standard 150 loads. Running at single or dual supply voltages ranging from 4.5 to 12 V, these amplifiers are tested at 5 V (2.5 V) and 10 V (5 V) supplies. The TSH81 also features a standby mode, which provides the operational amplifier with a low power consumption and high output impedance. This function allows power saving or signal switching/multiplexing for high-speed and video applications. For board space and weight saving, the TSH8x series is proposed in SOT23-5, TSSOP8, SO-8 and TSSOP14 plastic micropackages.

1. All voltage values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting terminal. 3. The magnitude of input and output must never exceed VCC +0.3 V. 4. Short-circuits can cause excessive heating. 5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of connected pin combinations while the other pins are floating. 7. Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins.

1. The IFR2026 synthesizer generates a two-tone signal (F1 = 180 kHz, F2 = 280 kHz), each tone having the same amplitude. The HP3585 spectrum analyzer measures the intermodulation products as a function of the output voltage. The generator and the spectrum analyzer are phase locked for better accuracy.

The HP3585 spectrum analyzer measures the intermodulation products as a function of the output voltage. The generator and the spectrum analyzer are phase locked for better accuracy.

Layout precautions
To make the best use of the TSH8X circuits at high frequencies, some precautions have to be taken with regard to the power supplies.
In high-speed circuit applications, the implementation of a proper ground plane on both sides of the PCB is mandatory to ensure low inductance and low resistance common return. Power supply bypass capacitors (4.7 F and ceramic 100 pF) 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 positive pins. All inputs and outputs must be properly terminated with output resistors; thus, the amplifier load is 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.

Time constants result from parasitic capacitance. To reduce time constants in lowergain applications, use a low feedback resistance (under 1 k). Choose the smallest possible component sizes (SMD). On the 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 the effect of the load capacitance.

Video capabilities
To characterize the differential phase and differential gain a CCIR330 video line is used. The video line contains five (flat) levels of luminance onto which the chrominance signal is superimposed. The luminance gives various amplitudes which define the saturation of the signal. The chrominance gives various phases which define the color of the signal. Differential phase (or differential gain) distortion is present if a signal chrominance phase (gain) is affected by the luminance level. The differential phase and gain represent the ability to uniformly process the high frequency information at all luminance levels. When a differential gain is present, color saturation is not correctly reproduced. The input generator is the Rhode & Schwarz CCVS. The output measurement is done by the Rhode and Schwarz VSA.

Precautions on asymmetrical supply operation

Precautions on asymmetrical supply operation
The TSH8x 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 so as to reject any noise present on the supply rail. As the bias current is 15 A, you should use a high resistance R1 (approximately 10 k) to avoid introducing an offset mismatch at the amplifier's inputs. Figure 33.

C1, C2, C3 are bypass capacitors intended to filter perturbations from VCC. The following capacitor values are appropriate. C1 = 100 nF and C2 = C3 = 100 F R2 and R3 are such that the current through them must be superior to 100 times the bias current. Therefore, you could use the following resistance values. R2 = R3 = 4.7 k Cin and Cout are chosen to filter the DC signal by the low pass filters (R1, Cin) and (Rout, Cout). With R1 = 10 k Rout = RL = 150 , and Cin = 2 F, Cout = 220 F the cutoff , frequency obtained is lower than 10 Hz. Figure 34. Use of the TSH8x in a gain = -1 configuration
