description
These devices consist of four independent, high- gain frequency-compensated Norton operational amplifiers that were designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies is also possible. The low supply current drain is essentially independent of the magnitude of the supply voltage. These devices provide wide band- width and large output voltage swing. The LM2900 is characterized for operation from –40°C to 85°C, and the LM3900 is characterized for operation from 0°C to 70°C. schematic (each amplifier) Constant Current Generator VCC 200 µA OUT 1.3 mAIN + IN – Copyright 1990, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.

The negative input currents that may result from large signal overdrive with capacitive input coupling must be limited externally to values of approximately –1 mA. Negative input currents in excess of –4 mA causes the output voltage to drop to a low voltage. These values apply for any one of the input terminals. If more than one of the input terminals are simultaneously driven negative, maximum currents are reduced. Common-mode current biasing can be used to prevent negative input voltages.

APPLICATION INFORMATION
Norton (or current-differencing) amplifiers can be used in most standard general-purpose operational amplifier applications. Performance as a dc amplifier in a single-power-supply mode is not as precise as a standard integrated-circuit operational amplifier operating from dual supplies. Operation of the amplifier can best be understood by noting that input currents are differenced at the inverting input terminal and this current then flows through the external feedback resistor to produce the output voltage. Common-mode current biasing is generally useful to allow operating with signal levels near (or even below) ground. Internal transistors clamp negative input voltages at approximately –0.3 V but the magnitude of current flow has to be limited by the external input network. For operation at high temperature, this limit should be approximately –100 µA. Noise immunity of a Norton amplifier is less than that of standard bipolar amplifiers. Circuit layout is more critical since coupling from the output to the noninverting input can cause oscillations. Care must also be exercised when driving either input from a low-impedance source. A limiting resistor should be placed in series with the input lead to limit the peak input current. Current up to 20 mA will not damage the device, but the current mirror on the noninverting input will saturate and cause a loss of mirror gain at higher current levels, especially at high operating temperatures. 1 MΩ 1 MΩ 1 MΩ 100 kΩ 91 kΩ 30 kΩ 1 kΩ10 kΩ Output Input IO ≈ 1 mA per input volt Figure 13.

In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown. Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board. (6) Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part. Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two combined represent the entire part marking for that device. Addendum-Page 1
