1) Input current and output amplifier characteristics:
"Output signal must be amplified and available at 2µs after input signal change (Gain 5...15)
2) Not subject to production test; specified by design
3) Without considering any offsets such as input offset voltage, internal miss match and assuming no tolerance error in
external resistors.
