- IL300XC Isolation Amplifier for TMP01 Temperature Sensor
This schematic diagram is about IL300XC Isolation Amplifier circuit for TMP01 Temperature Sensor. This circuit is used in an environment that needs to be electrically isolated from the central processing area. This circuit uses an 8-pin optoisolator (IL300XC). IL300XC was chosen because it can operate across a 5,000V. To drive the LED connected between Pin …[Read More]
- ADP1821 Step Down DC-to-DC Converter
This is a ADP1821 Step Down DC-to-DC Converter circuit. This circuit uses ADP1821 that is synchronous pulse-width-modulated (PWM), step-down controller, inexpensive and versatile. It can drive all N-channel power stage to regulate an output voltage as low as 0.6 V. The output voltages that can be provided by this circuit is from 0.6 V to …[Read More]
- AD596/597 Setpoint Control for Temperature Controller
This is a setpoint controller circuit using The AD596/AD597. The thermocouple voltage is amplified, compared to an external setpoint voltage, and cold junction compensated. The device temperature can be monitored if the temperature to be controlled is within the operating range (–55°C to +125°C) of the device. Here is the schematic diagram of the circuit: …[Read More]
Digitally Controlled Dual Polarity Amplifier
This schematic diagram below shows a Digitally Controlled Dual Polarity Amplifier circuit. The circuit (a) can give a means of amplifying a signal either in non inverting and inverting mode. When S2 is off and S1 is on, the noninverting input of the op amp is fed by the signal. The circuit behaves as a …[Read More]
Wheatston Bridge PWM Signal Conditioner
This is a schematic diagram of a Wheatston Bridge PWM Signal Conditioner circuit. This circuit uses the MAX1452 signal conditioner. A ratiometric compensated output for the Wheatstone Bridge is generated by the MAX1452. Then the output of the Wheatston bridge is converted to a PWM output. the PWM-output duty cycle changes accordingly, as the MAX1452 …[Read More]
