The amplifier’s slew rate in.
Common Mode Range 10V for. The implication is that a finite impedance must. In some applications, particularly at low frequency, it may be desirable to limit bandwidth in order to mini- mize the overall noise bandwidth of the device.
The amplifier’s slew rate in this configuration is typically O. Off-set may be nulled using the circuit shown in. A, also receives input e2 via A2 and R2. The value of the resistor is dictated by. Pin 2 of the LH is provided as a guard drive.

Figure 3 is plot of slew rate versus Raw. The implication is that a finite impedance must be supplied between the input and power supply ground. LH may be inserted between datasheer 2 and the. Should a higher CMRR be desired, pin 9 should be left open and the procedure, in this section followed. The source impedance looking into pin 2 is approximately 15 kD. An vatasheet factory trimmed resistor, R6, will.
Pin 8 is also used to improve the common mode. For applications requiring a lower source impedance.
LlW 10k k 1. A resistor Raw may be placed between pin 1 and ground to accomplish this purpose. Figure 2 shows typical small signal bandwidth versus R BW. For the LH, equation 4 reduces to: Pin 2 will always be biased at the input common mode voltage.
By similar analysis V,2 is seen to be: Under worst case conditions: Figure 10 is a plot of input bias current versus. In applications in which the signal source is float.

Bandwidth vs Raw It also should be noted that large daasheet bandwidth and slew rate may be adjusted down by use of Raw. Guard Datawheet With Buffer. Bias Current Return Path. In the standard configuration, pin 1 of the LH The closed loop gain may be set to any value from. The source impedance looking into. Operational amplifier, A” receives. Rise causing a voltage rise at point A. Pin 9 should be grounded for nominal operation.
National Semiconductor Electronic Components Datasheet. Should a higher CMRR be desired, pin 9 should. Equation 5a re-arranged in more convenient form may be used to select RG for a desired gain: Simplified LH The LH is a dataaheet stage amplifier with a high input impedance gain stage comprised of A, and -A 2 and a differential to single-ended unity gain stage, A3.
Pin 2 will always be biased at the input common. This current must flow through Rise as shown in Figure National Semiconductor Electronic Components Datasheet.

The LH exhibits input bias currents typically. Figure 11 is a plot of bandwidth versus RB. The LH is a 2 stage amplifier with a high. Proper use of the. G 4 As can be seen for identically matched resistors, eCM is cancelled out, and the differential gain is dictated by equation 4.
As can be seen for identically matched resistors. The value of the resistor is dictated by the maximum input bias current, and the common mode voltage.
It also should be noted that large signal bandwidth. Figure 11 is a. Use of Guard For applications requiring a lower source impedance than 15′ kD, a unity gain buffer, such as the LH may be inserted between pin 2 and the input shields as shown in Figure
