Note 1: Die parameters are production tested at room temperature only, but are guaranteed by design from TA = -40°C to +85°C.

AC characteristics guaranteed by design and characterization.

Note 2: GNOM = IMON (1mA) / 1mA.

Note 3: Stability is relative to the nominal gain at VCC = +3.3V, TA = +25°C. ΔG(IIN) dB = 10 log10 [ IMON(IIN) ] / [ IMON(1mA) - GNOM

x (1mA - IIN)], VMON ≤ 2.1V, Input tr, tf > 550ps (20% to 80%).

Note 4: Total noise integrated from 0 to f.
