general instructions
The AD8205 is a single-supply difference amplifier designed for
amplifies small differential voltages in the presence of large
common mode voltage.
Working Input Common Mode
The voltage range extends from −2 V to +65 V. A typical single supply voltage is 5 V.
The AD8205 is available in an 8-lead SOIC package rated for
Y and W grades operate from −40°C to +125°C
role model. The H-grade version of the AD8205 is rated at
−40°C to +150°C.
Excellent DC Performance Maintains Error Over Temperature
Measuring loops are reduced to a minimum. Offset drift is usually small
Above 15 µV/°C, gain drift is typically less than 30 ppm/°C.
Output Offset Adjustable from 0.05 V to 4.8 V
Use the VREF1 and VREF2 pins to provide 5 V power. With VREF1
connected to the V+ pin and VREF2 to the GND pin, then
The output is set to half. Connecting both pins to GND results in
The output is unipolar and starts near ground. append both
A pin tied to V+ causes the output to start unipolar around V+.
Other offsets can be obtained by applying an external voltage
VREF1 and VREF2 pins.
