TSH350ILT
550 MHz, Low Noise Current Feedback Amplifier
Bandwidth: 550MHz in unity gain Quiescent current: 4.1mA Slew rate: 940V/µs Input noise: 1.5nV/VHz Distortion: SFDR=-66dBc (10MHz, 1Vp-p) 2.8Vp-p min. output swing on 100Ω load for a 5V supply Tested on 5V power supply
DescriptionThe TSH350 is a current feedback operational
amplifier using a very high speed complementary
technology to provide a bandwidth up to 410MHz
while drawing only 4.1mA of quiescent current.
With a slew rate of 940V/µs and an output stage
optimized for driving a standard 100Ω load, this
circuit is highly suitable for applications where
speed and power-saving are the main
requirements.
The TSH350 is a single operator available in the
tiny SOT23-5 and SO8 plastic packages, saving
board space as well as providing excellent
thermal and dynamic performances.

TSH350 Absolute Maximum Ratings
1 Absolute Maximum Ratings
Table1: Key parameters and their absolute maximum ratings All voltages values are measured with respect to the ground pin. Differential voltage are non-inverting input terminal with respect to the inverting input terminal. The magnitude of input and output voltage must never exceed VCC +0.3V. Short-circuits can cause excessive heating. Destructive dissipation can result from short circuit on amplifiers. Human body model, 100pF discharged through a 1.5kΩ resistor into pMin of device. This is a minimum Value. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC withno external series resistor (internal resistor < 5Ω), into pin to pin of device.

Power Supply Considerations TSH350 Power Supply ConsiderationsCorrect power supply bypassing is very important for optimizing performance in high-frequency ranges.
Bypass capacitors should be placed as close as possible to the IC pins to improve high-frequency
bypassing. A capacitor greater than 1µF is necessary to minimize the distortion. For better quality
bypassing, a capacitor of 10nF can be added using the same implementation conditions. Bypass
capacitors must be incorporated for both the negative and the positive supply.
Note: On the SO8_SINGLE_HF board, these capacitors are C6, C7, C8, C9.
Single power supply In the event that a single supply system is used, new biasing is necessary to assume a positive output
dynamic range between 0V and +VCC supply rails. Considering the values of VOH and VOL, the amplifier
will provide an output dynamic from +0.9V to +4.1V on 100Ω load.
The amplifier must be biased with a mid-supply (nominally +VCC /2), in order to maintain the DC
component of the signal at this value. Several options are possible to provide this bias supply, such as a
virtual ground using an operational amplifier or a two-resistance divider (which is the cheapest solution).
A high resistance value is required to limit the current consumption. On the other hand, the current must
be high enough to bias the non-inverting input of the amplifier. If we consider this bias current (35µA
max.) as the 1% of the current through the resistance divider to keep a stable mid-supply, two resistances
of 750Ω can be used.
The input provides a high pass filter with a break frequency below 10Hz which is necessary to remove the
original 0 volt DC component of the input signal, and to fix it at +VCC/2.
Figure 31 illustrates a 5V single power supply configuration for the SO8_S_MULTI evaluation board (see
Evaluation Boards on page 10).
