which op-amp?

Trying to link a KMC-10 magnetic current sensor to a 16F73 ADC input, but also need a 0 to 10 volt aux output.

Because the sensor is a bridge (output in mV) am using a classic differential amplifier (1 op-amp, 4 resistors). To keep circuit simple decided to use a single ended op-amp, powered from a 7812 regulator.

Choosing the best op-amp proving a nightmare (no probs if I had a -12V rail), just unable to get the output to be 0V for no current I/P. So far had best results from a LM383, TLC271 and CA3160.

Wondered what amplifer others use for sensor signal conditioning?

We are currently using Intersils CA3140E and CA3240E. Both parts seem to work really good. The only problem that we seen was if we did not have a 100 ohm resistor on the output and a small AC signal back fed it would smoke it. With the 100R resistor in series it works flawless. We on use 2 resistors in ours which seems to work pretty good.

google search gives me

TL072 should work and it's very cheap
