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 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 3: 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.

Operation

The TP559x series op amps are zero drift, rail-to-rail operation amplifiers that can be run from a single-supply voltage.

They use an auto-calibration technique with a time-continuous 3.3 MHz op amp in the signal path while consuming

only 470 μA of supply current per channel. This amplifier is zero-corrected with an 120 kHz clock. Upon power-up, the

amplifier requires approximately 100 μs to achieve specified V_OSaccuracy. This design has no aliasing or flicker noise.

Applications Information

Rail-To-Rail Input And Output

The TP559x op-amps feature rail-to-rail input and output with a supply voltage from 1.8V to 5.5 V. This allows the

amplifier inputs to have a wide common mode range (50mV beyond supply rails) while maintaining high CMRR(127dB)

and maximizes the signal to noise ratio of the amplifier by having the V_OHand V_OLlevels be at the V+ and V- rails,

respectively.

Input Protection

The TP559x op-amps have internal ESD protection diodes that are connect between the inputs and supply rail. When

either input exceeds one of the supply rails by more than 300mV, the ESD diodes become forward biased and large

amounts of current begin to flow through them. Without current limiting, this excessive fault current causes permanent

damage to the device. Thus an external series resistor must be used to ensure the input currents never exceed 10mA.

Low Noise, 1.8V, 3.3MHz, RRIO, Zero Drift Op-amps

Low Input Referred Noise

Flicker noise, as known as 1/f noise, is inherent in semiconductor devices and increases as frequency decreases. So

at lower frequencies, flicker noise dominates, causing higher degrees of error for sub-Hertz frequencies or dc precision

application.

The TP559x op-amps are chopper stabilized amplifiers, the flicker noise is reduced greatly because of this technique.

This reduction in 1/f noise allows the TP559x to have much lower noise at dc and low frequency compared to standard

low noise amplifier.

Residual voltage ripple

The chopping technique can be used in amplifier design due to the internal notch filter. Although the chopping related

voltage ripple is suppressed, higher noise spectrum exists at the chopping frequency and its harmonics due to residual

ripple.

So if the frequency of input signal is nearby the chopping frequency, the signal maybe interfered by the residue ripple.

To further suppress the noise at the chopping frequency, it is recommended that a post filter be placed at the output of

the amplifier.

Broad Band And External Resistor Noise Considerations

The total broadband noise output from any amplifier is primarily a function of three types of noise: input voltage noise

from the amplifier, input current noise from the amplifier, and thermal (Johnson) noise from the external resistors used

around the amplifier. These noise sources are not correlated with each other and their combined noise can be

summed in a root sum squared manner. The full equation is given as:

e_ntotal  [e_n² 4kTR_s (i_n R_s)²]^1/2

Where:

e_n= the input voltage noise density of the amplifier.

i_n= the input current noise of the amplifier.

R_S= source resistance connected to the noninverting terminal.

k= Boltzmann’s constant (1.38x10^-23J/K). T= ambient temperature in Kelvin (K).

The total equivalent rms noise over a specific bandwidth is expressed as:

e_n,rms e_ntotal  BW

The input voltage noise density (en) of the TP559x is 17 nV/√Hz, and the input current noise can be neglected. When

the source resistance is 190 kΩ, the voltage noise contribution from the source resistor and the amplifier are equal.

With source resistance greater than 190 kΩ, the overall noise of the system is dominated by the Johnson noise of the

resistor itself.

High Source Impedance Application

The TP559x op-amps use switches at the chopper amplifier input, the input signal is chopped at 125kHz to reduce

input offset voltage down to 20µV . The dynamic behavior of these switches induces a charge injection current to the

input terminals of the amplifier. The charge injection current has a DC path to ground through the resistances seen at

the input terminals of the amplifier. Higher input impedance cause an apparent shift in the input bias current of the

amplifier.

Because the chopper amplifier has charge injection currents at each terminal, the input offset current will be larger

than standard amplifiers. The I_OSof TP559x are 150pA under the typical condition. So the input impedance should be

balanced across each input. The input impedance of the amplifier should be matched between the IN+ and IN-

terminals to minimize total input offset current. Input offset currents show up as an additional output offset voltage, as

shown in the following equation:

v_os,total v_os R_f I_os

For a gain configure using 1MΩ feedback resistor, a 150pA total input offset current will have an additional output

offset voltage of 0.15mV. By keeping the input impedance low and balanced across the amplifier inputs, the input

offset current effect will be suppress efficiently.

Circuit Implication for reducing Input offset current effect

PCB Surface Leakage

In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be

considered. Surface leakage is caused by humidity, dust or other contamination on the board. It is recommended to

use multi-layer PCB layout and route the OPA’s -IN and +IN signal under the PCB surface.

The effective way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is

biased at the same voltage as the sensitive pin. An example of this type of layout is shown in the Figure for Inverting

Gain application.

1. For Non-Inverting Gain and Unity-Gain Buffer:

a) Connect the non-inverting pin (V_IN+) to the input with a wire that does not touch the PCB surface.

b) Connect the guard ring to the inverting input pin (V_IN–). This biases the guard ring to the Common Mode input voltage.

2. For Inverting Gain and Trans-impedance Gain Amplifiers (convert current to voltage, such as photo detectors):

a) Connect the guard ring to the non-inverting input pin (V_IN+). This biases the guard ring to the same reference voltage as the

op-amp (e.g., V_DD/2 or ground).

b) Connect the inverting pin (V_IN–) to the input with a wire that does not touch the PCB surface.
