Wasn't there something very common missing on these like mA ability, just Amps ?
Full featured DMM's using this chipset have a fouth input jack: COM, V, mA/uA, A
AN8008 has three and is missing the low mA range, it has uA, high mA + A. So it reads:
0-99.99uA at the V jack with 100R shunt.
0-999.9uA at the V jack with 100R shunt.
0-999.9mA at the A jack with 0.01R shunt
0-9.999A at the A jack with 0.01R shunt
Missing is the 9.999mA/99.99mA range with 0.99R shunt.
So you can only get 0.1mA resolution on mA measurements.
Also, it cannot measure past 9.999MEG ohms
