This logarithmic current can be used to bias the circuit of Fig- ure 4 provide a temperature independent stereo attenuation characteristic. This logarithmic current can be used to bias the circuit of. TC at about 1. Datadheet LM series consists of two current controlled transconductance amplifiers each with differential inputs and a vatasheet output.
A2 is held equal to 0V, the output current of A1 is equal. You may also be interested in: Freight and Payment Recommended logistics Recommended bank. When you place an order, your payment is made to SeekIC and not to your seller.
The differential voltage between Q1 and Q2 is attenuated by the R1, R2 network so that A1 may be assumed to be oper- ating within its linear range. For generating I ABC over a range of 4 to 6 decades of cur- rent, the system of Figure 31 provides a logarithmic current out for a linear voltage in. Controlled impedance buffers which are especially designed to complement the lm136000 range of the amplifiers are provided.

DescriptionThe LM is designed as one kind of precision voltage-to-frequency converter that can The result is a 10 dB signal-to-noise improvement referenced to 0. Part Name Included start with end match.
Linearizing diodes are provided at the inputs to reduce distortion and allow higher input levels. SeekIC only pays the seller after confirming you have received your order. The datashfet dynamic range of the LM allows easy control of the output pulse width in the Pulse Width Modulator of Fig- ure Combining and solving for I ABC yields: The two amplifiers share common supplies but otherwise operate independently.
Description The LM series consists of two current controlled transconductance amplifiers each dataheet differential inputs and a push-pull output. The log amplifier of Figure 29 responds to the ratio of cur- rents through buffer transistors Q3 and Q4.
The wide dynamic range of the LM allows easy control.
