Hi,
We want help regarding a design where we have to amplify a DAC output to a large voltage level
We are getting a analog voltage output from a 12-bit DAC port of our micro-controller. The analog output voltage range is 0V to 1.8V. As per the 12-bit DAC, the minimum LSB voltage is 1.8/4096= 439uV and maximum voltage is 1.8V
Now we want to scale up or translate the DAC voltage range from (439uV --- 1.8V ) to (800uV----- 3.3V).
Since the DAC output voltages are in micro volts we are bit confused whether to use a general pupose or any instrumentation amplifier
Can you share any suitable application design which can perform above scaling up or translation of voltage range?
