LM OP Amp operating characteristics. A feedback pole is created when the feedback around any amplifier is resistive. Gain bandwidth unity gain: For input voltages which greatly exceed the maximum supply voltages, either differentially or common-mode, resistors should be placed in series with the inputs to limit the current. Large Signal Pulse Response.

LM348 SMT Quad Op Amp IC

A high-gain dc amplifier that has extremely high voltage gain. Output Short Circuit Current. Other features include input offset currents and input bias current which are much less than those of a standard Low supply current drain. Any of the amplifier outputs can be shorted to ground indefinitely; however, more than one should not be simultaneously shorted lm384 the maximum junction temperature will be exceeded.

If the negative limit of the operating common-mode range is exceeded at both inputs, the output voltage will be positive. The value of the added capacitor should be such that the RC time constant of this capacitor and the resistance it parallels is greater than or equal to the original feedback pole time constant.

The input characteristics of these amplifiers allow differential input voltages which can exceed the supply voltages. Ceramic Lead Temperature Soldering, 10 sec.

Human body model, 1. High degree of isolation between amplifiers: In addition, the amplifier outputs are located in the corners of the package which simplifies PC board layout and minimizes package related capacitive catasheet between amplifiers. In addition the total supply.

Output voltage swing vs Sink Current mA. Inverting Large Signal Pulse Response. Like the LM, these amplifiers can easily drive a pF capacitive load throughout the entire dynamic output voltage and current range. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected datsheet cause the failure of the life support device or system, or to affect its safety or effectiveness.

Science Physics Electronics Data Sheet current advertisement. The package pin-outs are such that the inverting input of each amplifier is adjacent to its output. Lowpass Response 11 www. It consists of four independent, high gain, internally compensated, low power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar operational amplifier.

In the proliferation of quad op amps, these are the first to offer the convenience of familiar, easy to use operating characteristics of the op amp. Datahseet consists of four. Life support devices or systems are devices or systems.

Output voltage swing vs Source Current mA. Open Loop Frequency Datasheeet. Output Impedance vs Xatasheet. Low input offset current: All capacitors are 0. Output Short Circuit Duration. However, if very large capacitive loads must be driven by a non-inverting unity gain amplifier, a resistor should be placed between the output and feedback connection and the capacitance to reduce the phase shift resulting from the capacitive loading.

Typical Performance Characteristics continued. Supply Current vs Supply voltage. As with most amplifiers, care should be taken lead dress, component placement and supply decoupling in order to ensure datasheet. Class AB output stage no crossover distortion. Short circuits from an output to either ground dstasheet the power supplies will not destroy the unit.

In those applications where op amps have been employed, the LM series op amps can be employed directly with no change in circuit performance.

In addition the total supply current for all four amplifiers is comparable to the supply current of a single type op amp. C, unless otherwise specified. Power Supply Rejection Ratio. In many instances the frequency of this pole is much greater than the expected 3 dB frequency of the closed loop gain and consequently there is negligible effect on stability margin.

However, if the feedback pole is less than approximately six times the datqsheet 3 dB frequency a lead capacitor should be placed from the l348 to the input of the op amp. Low input bias current: Overload protection for inputs and outputs.

Data Sheet (current)

For lower power refer to LF In addition, if either of the input voltages is within the operating common-mode range, the phase of the output remains correct. Supply Current all Amplifiers. Undistorted Output Voltage Swing vs Frequency.
