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 s upply, 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 vol tage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified val ues are for short traces connected to the leads.

OUT: Amplifier Output. The voltage range extends to within mV of each supply rail. V+ or +Vs: Positive Power Supply. Typically the voltage is from 2.2V to 5.5V. Split supplies are possible as long as the voltage between V+ and V– is between 2.2V and 5.5V. A bypass capacitor of 0.1μF as close to the part as possible should be used between power supply pins or between supply pins and ground. V- or -V s: Negative Power Supply. It is normally tied to ground. It can also be tied to a voltage other than ground as long as the voltage between V+ and V– is from 2.2V 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. Operation The TP2301 series op amps can operate on a single-supply voltage (2.2 V to 5.5 V), or a split-supply voltage (±1.1 V to ±2.75 V), making them highly versatile and easy to use. The power-supply pins should have local bypass ceramic extended temperature range of –40°C to +125°C. Parameters that can exhibit variance with regard to operating voltage or temperature are presented in the Typical Characteristics Applications Information Input ESD Diode Protection The TP2301 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 10 mA as stated in the Absolute Maximum Ratings table. Many input signals are inherently current-limited to less than 10 mA; therefore, a limiting resistor is not required. Figure 1 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. Figure1. Input ESD Diode

20MHz Bandwidth, Low Noise High Precision Op‐amps w w w . 3 p e a k i c . c o m R e v . A Power Supply Layout and Bypass The TP2301/2302/2302 OPA’s power supply pin (V DD for single-supply) should have a local bypass capacitor (i.e., within 100mm to provide large, slow currents. This bulk capacitor can be shared with other analog parts. Ground layout improves performance by decreasing the am ount of stray capacitance and noise at the OPA’s inputs and outputs. To decrease stray capacitance, minimize PC board lengths and resistor leads, and place external components as close to the op amps’ pins as possible. Proper Board Layout To ensure optimum performance at the PCB level, care mu st be taken in the design of the board layout. To avoid leakage currents, the surface of the board should be kept cl ean and free of moisture. Coating the surface creates a barrier to moisture accumulation and helps reduce parasitic resistance on the board. Keeping supply traces short and properly bypassing the power supplies minimizes power supply disturbances due to output current variation, such as when driving an ac signal into a heavy load. Bypass capacitors should be connected as closely as possible to the device supply pins. Stray capacitances are a concern at the outputs and the inputs of the amplifier. It is recommended that signal traces be kept at least 5mm from supply lines to minimize coupling. A variation in temperature across the PCB can cause a mism atch in the Seebeck voltages at solder joints and other points where dissimilar metals are in contact, resulting in thermal voltage errors. To minimize these thermocouple effects, orient resistors so heat sources warm both ends equally. Input signal paths should contain matching numbers and types of components, where possible to match the num ber and type of thermocouple junctions. For example, dummy components such as zero value resistors can be us ed to match real resistors in the opposite input path. Matching components should be located in close proximity and should be oriented in the same manner. Ensure leads are of equal length so that thermal conduction is in equilibrium. Keep heat sources on the PCB as far away from amplifier input circuitry as is practical. The use of a ground plane is highly recommended. A ground plane reduces EMI noise and also helps to maintain a constant temperature across the circuit board. 20pfk H z Three-Pole Low-Pass Filter
