*Please help me
A circuit or ic with 20 volt input
and -10 mv to +10 mv, 350 mA output.this circuits is useful for instrumentation.all of voltage is DC.As you know 20 V is power supply,we want to control voltage with a variable resistor that gives 350 mA.I have two challenge with this circuits first,negative output voltage,second a high current in output.like a voltage divider circuits that is very simple.as u know this is a milivlot source maybe a power supply.precision is not very important.a circuit near this factors would be ok. we want to use this circuit for an indicator.
