Note 3: Modulation current gain, G MOD, is defined as G MOD = I MOD / I MODSET. Bias current gain, G BIAS, is defined as G BIAS = I BIAS / I BIASSET. The nominal gain is measured at = +3.3V and T A = +25 C. Note 4: Gain stability is defined as [(Gain) - (Nom_Gain)] / (Nom_Gain) over the listed current range, temperature, and supply variation. Nominal gain is measured at = +3.3V, T A = +25 C. The voltage at the BC_MON pin must not exceed 1.39V. Note 5: Guaranteed by design and characterization; see Figure 2. Note 6: turn-on time must be less than 0.8s, DC-coupled interface. Note 7: The gain matching is defined as ABS [(G MOD /G BIAS - G MODNOM /G BIASNOM )/(G MODNOM /G BIASNOM )] over the specified temperature and voltage supply range. Note 8: For supply noise tolerance, noise is added to the supply (0mV P-P ) up to 2MHz; see Figure 3. 3
