Description
3PEAK
Features
The TPH2501/3, THP2502, TPH2504 are single, dual,
quad low power, high speed unity gain stable rail-to-rail
input/output operational amplifiers. On only 6.5mA of
supply current they feature an impressive 250MHz gain-
bandwidth product, 180V/μs slew rate and a low
6.5nV/√Hz of input-referred noise, TPH2503 offers a
shutdown current of only 1μA. The combination of high
bandwidth, high slew rate, low power consumption and
low broadband noise makes these amplifiers unique
among rail-to-rail input/output op amps with similar
supply currents. They are ideal for lower supply voltage
high speed signal conditioning systems.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating
condition for extended periods may affect device reliability and lifetime.
Note 2: The op amp supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500Mv beyond the power supply, the input
current should be limited to less than 10Ma.
Note 4: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.

as long as the voltage between V+ and V– is from 2.5V to
5.5V. If it is not connected to ground, bypass it with a
capacitor of 0.1Μf as close to the part as possible.

as the voltage between V+ and V– is between 2.5V and
5.5V. A bypass capacitor of 0.1Μf as close to the part as

Operation
The TPH2501,TPH2502,TPH2504 is a CMOS, rail-to-rail I/O, high-speed, voltage-feedback operational amplifier
designed for video, high-speed, and other applications. It is available as a single, dual, or quad op amp. The amplifier
features a 250MHz gain bandwidth, and 180V/μs slew rate, but it is unity-gain stable and can be operated as a +1V/V
voltage follower. The TPH2501/TPH2502/TPH2504 is specified over a power-supply range of +2.7V to +5.5V (±1.35V
to ±2.75V). However, the supply voltage may range from +2.5V to +5.5V (±1.25V to ±2.75V). Supply voltages higher
than 7.5V (absolute maximum) can permanently damage the amplifier. Parameters that vary over supply voltage or
temperature are shown in the typical characteristics section of this datasheet.
Applications Information
Power On Requirement
Generally the high speed amplifier(>100MHz GBW) has larger Vos as the input transistors has small size to get the
lower input capacitance for high speed, the small size input transistors bring to large Vos for the mismatch of input
transistor pair. The high speed amplifier has normally >±5mV Vos, comparing to low speed amplifier has maximum
±3mV Vos with larger input transistors.
The TPH250x amplifier use internal calibration block to achieve ±2mV Vos, which is better than most of high speed
amplifiers. To guarantee the calibration block works properly, good power on of the amplifier power supply is
recommended:
Fast power on time to produce the power on reset signal of calibration block. The maximum value of power on time
is 1ms.
Avoid the voltage glitch reaching in 0.4V to 1V range on power supply. For example, power supply drop to 0.5V
then recovery to 5V may cause error of calibration block.
If the power on signal is not good, the amplifier has probability to enter an unexpected status.
Rail-to-Rail Inputs and Outputs
The TPH2501,TPH2502,TPH2504 op amps are designed to be immune to phase reversal when the input pins exceed
the supply voltages, therefore providing further in-system stability and predictability. Figure 1 shows the input voltage
exceeding the supply voltage without any phase reversal.

Figure 1. No Phase Reversal
Choice of Feedback Resistor and Gain Bandwidth Product
For applications that require a gain of +1, no feedback resistor is required. Just short the output pin to the inverting input
pin. For gains greater than +1, the feedback resistor forms a pole with the parasitic capacitance at the inverting input.
As this pole becomes smaller, the amplifier’s phase margin is reduced. This causes ringing in the time domain and
peaking in the frequency domain. Therefore, RF has some maximum value that should not be exceeded for optimum
performance. If a large value of RF must be used, a small capacitor in the few Pico farad range in parallel with RF can
help to reduce the ringing and peaking at the expense of reducing the bandwidth. As far as the output stage of the
amplifier is concerned, the output stage is also a gain stage with the load. RF and RG appear in parallel with RL for gains
other than +1. As this combination gets smaller, the bandwidth falls off. Consequently, RF also has a minimum value
that should not be exceeded for optimum performance. For gain of +1, RF=0 is optimum. For the gains other than +1,
optimum response is obtained with RF between 300Ω to 1Kω.
The TPH2501, TPH2502 and TPH2504 have a gain bandwidth product of 120MHz. For gains ≥5, its bandwidth can
be predicted by the following equation:
Gain × BW = 120MHz
Video Performance
For good video performance, an amplifier is required to maintain the same output impedance and the same frequency
response as DC levels are changed at the output. This is especially difficult when driving a standard video load of 150Ω,
because the change in output current with DC level. Special circuitry has been incorporated in the TPH2501, TPH2502
and TPH2504 to reduce the variation of the output impedance with the current output. This results in Dg and Dp
specifications of 0.03% and 0.3°, while driving 150Ω at a gain of 2. Driving high impedance loads would give a similar
or better Dg and Dp performance.
Driving Capacitive Loads and Cables
The TPH2501, TPH2502 and TPH2504 can drive 10Pf loads in parallel with 1Kω with less than 5Db of peaking at gain
of +1. If less peaking is desired in applications, a small series resistor (usually between 5Ω to 50Ω) can be placed in
series with the output to eliminate most peaking. However, this will reduce the gain slightly. If the gain setting is greater
than 1, the gain resistor RG can then be chosen to make up for any gain loss which may be created by the additional
series resistor at the output. When used as a cable driver, double termination is always recommended for reflection-

free performance. For those applications, a back-termination series resistor at the amplifier’s output will isolate the
amplifier from the cable and allow extensive capacitive drive. However, other applications may have high capacitive
loads without a back-termination resistor. Again, a small series resistor at the output can help to reduce peaking.
Output Drive Capability
The TPH2501,TPH2502 and TPH2504 output stage can supply a continuous output current of ±100Ma and still provide
approximately 2.7V of output swing on a 5V supply. For maximum reliability, it is not recommended to run a continuous
DC current in excess of ±100Ma. Refer to the typical characteristic curve Output Voltage Swing vs Output Current. For
supplying continuous output currents greater than ±100Ma, the TPH250x may be operated in parallel. The TPH250x
will provide peak currents up to 200Ma, which corresponds to the typical short-circuit current. Therefore, an on-chip
thermal shutdown circuit is provided to protect the TPH250x from dangerously high junction temperatures. At 160°C,
the protection circuit will shut down the amplifier. Normal operation will resume when the junction temperature cools to
below 140°C.
Single Supply Video Line Driver
The TPH2501, TPH2502 and TPH2504 are wideband rail-to-rail output op amplifiers with large output current, excellent
Dg, Dp, and low distortion that allow them to drive video signals in low supply applications. Figure 2 is the single supply
non-inverting video line driver configuration inverting video ling driver configuration. The signal is AC coupled by C1. R1
and R2 are used to level shift the input and output to provide the largest output swing. RF and RG set the AC gain. C2
isolates the virtual ground potential. RT and R3 are the termination resistors for the line. C1, C2 and C3 are selected
big enough to minimize the droop of the luminance signal.

Power Supply Bypassing and Printed Circuit Board Layout
As with any high frequency device, a good printed circuit board layout is necessary for optimum performance. Lead
lengths should be as sort as possible. The power supply pin must be well bypassed to reduce the risk of oscillation. For
normal single supply operation, where the VS- pin is connected to the ground plane, a single 4.7Μf tantalum capacitor
in parallel with a 0.1Μf ceramic capacitor from VS+ to GND will suffice. This same capacitor combination should be
placed at each supply pin to ground if split supplies are to be used. In this case, the VS- pin becomes the negative supply
rail. For good AC performance, parasitic capacitance should be kept to a minimum. Use of wire wound resistors should
be avoided because of their additional series inductance. Use of sockets should also be avoided if possible. Sockets
add parasitic inductance and capacitance that can result in compromised performance. Minimizing parasitic capacitance
at the amplifier’s inverting input pin is very important. The feedback resistor should be placed very close to the inverting
input pin. Strip line design techniques are recommended for the signal traces.
Video Sync Pulse Remover
Many CMOS analog to digital converters have a parasitic latch up problem when subjected to negative input voltage
levels. Since the sync tip contains no useful video information and it is a negative going pulse, we can chop it off. Figure
29 shows a gain of 2 connections. Figure 3 shows the complete input video signal applied at the input, as well as the
output signal with the negative going sync pulse removed.

Input ESD Diode Protection
The TPH250x incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case of input and
output pins, this protection primarily consists of current-steering diodes connected between the input and power-supply
pins. These ESD protection diodes also provide in-circuit input overdrive protection, as long as the current is limited to
20 Ma as stated in the Absolute Maximum Ratings table. Many input signals are inherently current-limited to less than
20 Ma; therefore, a limiting resistor is not required. Figure 4 shows how a series input resistor (RS) may be added to the
driven input to limit the input current. The added resistor contributes thermal noise at the amplifier input and the value
should be kept to the minimum in noise-sensitive applications.
