photodiode isolation amplifier circuit

Published:2011/5/7 11:30:00 Author:John | Keyword: photodiode, Isolation amplifier circuit

Photodiode isolation amplifier circuit makes the use of photodiode in order to provide reliable isolation between signal channel and power channel. IS0212P is a transformer coupled isolation amplifier circuit in small size and low cost. The inside chip uses two small but high-efficiency toroidal transformers, providing reliable isolation between signal channel and power channel. The firgue above shows the typical application in Photodetector. Photodiode BPW21 is parallelly set in two input ends of the OPAl28 (N1), causing the composition of I / U resistor gain. It adopts the amplifier feedback resistor. The selected op-amp with high impedance and low bias current aims to reduce the influence on photoelectric detection accuracy of the amplifier bias current. Amplifier OPA128 is powered by the ± V isolated power inside of the isolation amplifier ISO212P. Voltage signal of 1 / U is transformed by l00kΩ resistor into the inverting end of the input amplifier inside of IS0212P. Since the feedback resistor is R3 is also due to 100kΩ, the gain is -l.   (View)

The precision composite buffer circuit compose of the MC1458

Published:2011/5/8 9:06:00 Author:TaoXi | Keyword: precision composite buffer

The precision composite buffer is as shown. The pre-stage of the circuit is the voltage follower that is composed of the precision op amp LM11, the parallel part of rear-stage uses the general dual op amp MC1458 (or MC1558 dual operational amplifier). The input signal adds to the same-phase input port (pin 3) of the pre-stage through R1 (10kΩ), pin 8 links the 330pF compensation capacitor C1 to achieve the over compensation, the objective is to improve the bandwidth and slew rate of the Parallel output buffer stage, sometimes we connect the 100pF capacitor C2 between the pre-stage's output port (pin 6) and the inverting input port (pin 2) to improve the stability of the circuit. Between the pre-stage's output port and the inverting input port, there are two diodes D1 and D2 (model is 1N914), the role is to clamp when LM11 is overdriven, to reduce the blocking tendency and to minimize the recovery time. Add the 10kΩ resistor R2 between the circuit's total output port and the pre-stage LM11's inverting input port, this resistance leads the depth voltage series negative feedback to make the op amp working in linear state. The main parameters (typical) of the dual op amp 1458 (1558):   (View)
