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 Ω 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 device 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, SO-8, TSSOP8,
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 kΩ 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 Ω). 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.

3 Test conditions
3.1 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 µF 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 lower-
gain applications, use a low feedback resistance (under 1 kΩ).
●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.

3.2 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 Rohde & Schwarz CCVS. The output measurement is done by
the Rohde and Schwarz VSA.

TSH80, TSH81, TSH82, TSH84Precautions on asymmetrical supply operation
4 Precautions on asymmetrical supply operation
The TSH8x device 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
carefully designed so as to reject any noise present on the supply rail.
As the bias current is 15 µA, you should use a high resistance R1 (approximately 10 kΩ) to
avoid introducing an offset mismatch at the amplifier’s inputs.

C1, C2, C3 are bypass capacitors intended to filter perturbations from V
. The following
CC
capacitor values are appropriate.
C1 = 100 nF and C2 = C3 = 100 µF
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.
