All voltage values (except differential voltages and VS specified for the measurement of ISC) are with respect to the network GND. 2. Differential voltages are at +IN, with respect to -IN. OVERSTRESS CAUTION Stresses beyond those listed in Absolute Maximum Ratings may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Functional operation of the device at any conditions beyond those indicated in the Recommended Operating Conditions section is not implied.

ESD SENSITIVITY CAUTION This integrated circuit can be damaged if ESD protections are not considered carefully. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because even small parametric changes could cause the device not to meet the published specifications. DISCLAIMER SG Micro Corp reserves the right to make any change in circuit design, or specifications without prior notice.

DETAILED DESCRIPTION The LM2904 consists of two independent, high-gain frequency-compensated operational amplifiers designed to operate from a single supply over a wide range of voltages. Operation from dual supplies is also possible if the difference between the two supplies is 3V to 32V, and VS is at least 1.5V more positive than the input common mode voltage.

Applications include transducer amplifiers, DC amplification blocks, and all the conventional operational amplifier circuits that now can be implemented more easily in single-supply-voltage systems. For example, the device can be operated directly from the standard 5V supply used in digital systems and can easily provide the required interface electronics without additional ±5V supplies.

Unity-Gain Bandwidth The unity-gain bandwidth is the frequency up to which an amplifier with a unity gain may be operated without greatly distorting the signal. The device has a 1.1MHz unity-gain bandwidth.

Slew Rate The slew rate is the rate at which an operational amplifier can change its output when there is a change on the input. The device has a 0.35V/μs slew rate.

Input Common Mode Range The valid common mode voltage range is from device ground to VS - 1.5V. Inputs may exceed VS up to the maximum VS without device damage. At least one input must be in the valid input common mode voltage range for output to be correct phase. If both inputs exceed valid range then output phase is undefined. If either input is less than -0.3V then input current should be limited to 1mA and output phase is undefined.

Device Functional Modes The device is powered on when the supply is connected. This device can be operated as a single-supply operational amplifier or dual-supply amplifier depending on the application.

APPLICATION INFORMATION The LM2904 operational amplifier is useful in a wide range of signal conditioning applications. Inputs can be powered before VS for flexibility in multiple supply circuits.

Typical Application A typical application for an operational amplifier is an inverting amplifier. This amplifier takes a positive voltage on the input and makes it a negative voltage of the same magnitude. In the same manner, it also makes negative voltages positive.

Figure 1. Application Schematic

The supply voltage must be chosen such that it is larger than the input voltage range and output range. For instance, this application will scale a signal of ±0.5V to ±1.8V. Setting the supply at ±12V is sufficient to accommodate this application.

Determine the gain required by the inverting amplifier using Equation 1 and Equation 2:

OUTV

IN

VA = V

(1)

V1.8A = = -3.6-0.5

(2)

Once the desired gain is determined, choose a value for RI or RF. Choosing a value in the kΩ range is desirable because the amplifier circuit will use currents in the milliamp range. This ensures the part will not draw too much current. This example will choose 10kΩ for RI which means 36kΩ will be used for RF. This was determined by Equation 3.
