Running with a single supply voltage from 3 V to 2 V, these amplifiers feature a large output voltage swing and high output current capable of driving standard Ω loads. A low operating voltage makes TSH7x amplifiers ideal for use in portable equipment. The TSH7, TSH73, and TSH7 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-, SO, and TSSOP packages. December 23 DocID72 Rev 4 /36 This is information on a product in full production. www.st.com

TSH7x Testing conditions 4 Testing conditions 4. 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 on 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 (4.7 µf and ceramic 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 the positive pins. Proper termination of all inputs and outputs must be in accordance with output termination resistors. In this way, the amplifier load is resistive only, and the stability of the amplifier is 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 (> kω) 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. DocID72 Rev 4 2/36 36
Testing conditions TSH7x 4.2 Maximum input level Figure 47. CCIR33 video line The input level must not exceed the following values: Negative peak: must be greater than -V CC 4 mv Positive peak value: must be lower than V CC -4 mv The electrical characteristics show the influence of the load on this parameter. 4.3 Video capabilities To characterize the differential phase and differential gain, a CCIR33 video line is used. The video line contains five (flat) levels of luma on which is superimposed a 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 and Schwarz CCVS. The output measurement was made by the Rohde and Schwarz VSA. 22/36 DocID72 Rev 4

Testing conditions TSH7x 4.4 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 (V CC /2). This bias network must be carefully designed, in order to reject any noise present on the supply rail. As the bias current is µa, you must carefully choose the resistance R so as not to introduce an offset mismatch at the amplifier inputs. Figure 49. Schematic of asymmetrical (single) supply IN C in R R2 Vcc C3 - R C out OUT R L R3 C C2 Cf R4 R = kω is a typical and convenient value. C, C2, C3 are bypass capacitors that filter perturbations on V CC, as well as for the input and output signals. We choose C = nf and C2 = C3 = µf. R2, R3 are such that the current through them must be greater than times the bias current. Therefore, we set R2 = R3 = 4.7 kω. C in, as C out, is chosen to filter the DC signal by the low-pass filters (R,C in and R out, C out ). By taking R = kω, R L = Ω, and C in = 2 µf, C out = 22 µf we provide a cut-off frequency below Hz. Figure.
