Pin 2 will always be biased at the input common. In applications in which the signal source is float. For the LH, equation 4 reduces to: Should a higher CMRR be desired, pin 9 should. As can be seen for identically matched resistors. The source impedance looking into. Figure 2 shows typical small signal bandwidth versus R BW. By similar analysis V,2 is seen to be: The amplifier’s slew rate in this configuration is typically O. The value of the resistor is dictated by.
A resistor Raw may be placed between pin 1 and ground to accomplish this purpose.

LlW 10k k 1. In the standard configuration, pin 1 of the LH It also should be noted that large signal bandwidth. The closed loop gain may be set to any value from. For applications requiring a lower source impedance. Operational amplifier, A” receives.
Pin 2 of the LH is provided as a guard drive. Common Datashete Range 10V for. Off-set may be nulled using the circuit shown in. The amplifier’s slew rate in. Pin 9 should be grounded for nominal operation.

Bias Current Return Path. The LH is a 2 stage amplifier with a high.
The LH exhibits input bias currents typically. Rise causing a voltage rise at point 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 datashwet shown in Figure Equation 5a re-arranged in more convenient form may be used to select RG for a desired gain: Should a higher CMRR be desired, pin 9 should be left open and the procedure, in this section followed.
Pin 8 is also used to improve the common mode. National Semiconductor Electronic Components Datasheet. Simplified LH The LH is a 2 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.
Figure 11 is a plot of bandwidth versus RB. Guard Pin With Buffer. Under worst case conditions: This current must flow through Rise as shown in Figure The implication is that a finite impedance must. LH may be inserted between pin 2 and the. National Semiconductor Electronic Components Datasheet. A, also receives input e2 via A2 and R2. G 4 As can be seen for identically matched resistors, eCM is cancelled out, and the differential gain is dictated by equation 4.
Proper use of the. 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.
Figure 10 is a plot of input bias current versus. The source impedance looking into pin 2 is approximately 15 kD. An internal factory trimmed resistor, R6, will. The implication is that a finite impedance must be supplied between the input and power supply ground.
The value of the resistor is dictated by the maximum input bias current, and the common mode voltage. Bandwidth vs Raw It also should be noted that large signal bandwidth and slew rate may be adjusted down by use of Raw.
