Subject: A/D Question, About Larrys Boards

Hello PSN,

Can anyone tell me if Larry's 16 bit boards
go 16 bits plus or minus or if they go
15 bits plus or minus ?

It will make a difference in calculating volts per count ?

2^16 = 0 to 65535 with the circuitry somehow giving a full 16 bits both plus or minus
2^16 = 0 to 32767 with the msb as a sign bit for negative voltages

I could test but know someone else already knows.
