5.3
The TLE7183F incorporates a fast and precise operational amplifier for conditioning and amplification of the
current sense shunt signal. Additionally, one reference bias buffer is integrated to provide an adjustable bias
reference for the three OpAmps. The voltage devider on the VRI pin should be less than 50 kOhm, the filtering
capacitor less than 1.2 µF - if needed at all. The gain of the OpAmp is adjustable by external resistors within a
range of 5 to 15.
When V(ISP) = V(ISN), VO provides the reference voltage VRO. VRO is normally half of the regulated voltage
provided from an external voltage regulator for the ADC used to read the current sense signal. The additional
buffer allows bi-directional current sensing and permits the adaptation of the reference bias to different µC I/O
voltages. The reference buffer assures a stable reference voltage even in the high frequency range.
The output of the I-DC link Opamp Vo is not short-circuit proof.
