Hello all.
My latest project(plaything) is a 3 axis +/- 3g accelerometer based on the ADXL330.
I am using a board with a 3.3V power supply. 0g on each axis is approximately half that, 1.66 V , my maximum range is going to be 0V to 3.3V. signal on each output.
My Board specs are:
Triple axis =/-3g sense range.
Upto 360mV/g sensitivity
500Hz bandwidth
Internal 3.3V regulator
External operating voltage 3.5V to 15V
Integrated power supply decoupling
Draws 0.9mA
Can accurately drive 500Ohm Loads
What I would like to do is use a suitable OpAmp so that I can offset 0g to 0Volts and also amplify my signals so the output voltage range would be close to +/- 5V , i.e. + 3g=5V 0g=0V -3g=-5v . My outputs will normally be feeding 3 channels of my 4 channel Picoscope
Datasheet attached
Can anyone recommend a suitable low noise Opamp, ideally one that can handle all three inputs.
