Description

The TP2331/TP2332/TP2334 are single/dual/quad, low offset, low noise operational amplifiers with low power consumption and rail-to-rail input/output swing. Input offset voltage is trimmed to less than 50μV and the CMOS inputs draw less than 0.3pA of bias current. The low offset drift, excellent CMRR, and high voltage gain make it a good choice for precision signal conditioning. Each amplifier draws only 190μA current on a 3V supply. The micro power, rail-to-ra il operation of the TP233x series is well suited for portable instruments and single supply applications. The TP2331 is single channel version available in 8-pin SOP and 5-pin SOT23 packages. The TP2332 is dual channel version available in 8-pin SOP and MSOP packages. The TP2334 is quad channel version available in 14-pin SOP and TSSOP packages. 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.

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.

1.6MHz Bandwidth, Low Noise Precision Op‐amps w w w . 3 p e a k i c . c o m R e v . A 1. For Non-Inverting Gain and Unity-Gain Buffer: a) Connect the non-inverting pin (VIN+) 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., VDD/2 or ground). b) Connect the inverting pin (V IN–) to the input with a wire that does not touch the PCB surface. Figure 6 The Layout of Guard Ring Power Supply Layout and Bypass The TP2331/2332/2332 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.
