Am402 is a voltage to current converter ic with integrated protection functions and voltage source.
High side voltage to current v i converter.
I do find that with 1 amp flowing through the string of led arrays that voltage across each one is about 3 77 v.
Converts voltage to current.
Good compliance voltage to the both rails.
Single supply solution with rail to rail input dual channel op amp.
For the circuit analysis we have to first determine the voltage v in and then the relationship or the connection between the input voltage and load current can be achieved.
I e the currents entering into the 2 input terminals is very small.
For this reason voltage to current converters are employed.
Open loop gain a of the op amp is very large.
That only leaves about about the 1 4 v across the output mosfet and rs3.
Multiply that times 6 and the string has 22 6 v across it.
Design creates a current source that allows for a gnd referenced load.
When we discuss concerning the relationship between voltage and current it becomes evident to refer to the ohm s law.
Simple voltage to current converter.
The gate to source voltage is over 20 v way too high and the mosfet is in saturation.
It can easily transform the carrier of electrical data from voltage to current.
V i x r.
I b i b2.
This v to i converter is also known as howland current converter.
Input impedance of the op amp is very high.
High sidevoltage to current v i converter ti precision designs circuit description ti precision designs are analog solutions created by this high sidevoltage to current v i converter ti s analog experts.
Here one end of the load is always grounded.
Current to voltage converter i v.
Sensitivity of the i v converter.
It converts a differential input voltage into a current output signal with adjustable offset and gain.
Verified designs offer the theory delivers a well regulatedcurrent to a ground component selection simulation complete pcb referenced load.
V 1 v 2 1 a.
The output voltage v 0 r f i in.
Excellent dc performance and temperature drift using zero drift opa2333 op amp.
Am402 is particularly suitable for industrial sensing and signal conditioning in two or three wire applications.
Voltage to current v to i converter linear applications of op amp linear integrated circuits duration.
