LT6658
TYPICAL PERFORMANCE CHARACTERISTICS TA = 25°C, VIN = VIN1 = VIN2 = VOUT1_F + 2.5V = VOUT2_F + 2.5V except LT6658-1.2 where VIN = VIN1 = VIN2 = 4.5V, COUT1 = COUT2 = 1µF, ILOAD = 0mA, unless otherwise noted. The characteristic curves are similar across the LT6658 family. Curves from the LT6658-1.2, LT6658-2.5 and the LT6658-5 represent the full range of typical performance of all voltage options. Characteristic curves for other output voltages fall between these curves and can be estimated based on their output. 1.2V Channel to Channel Load 1.2V Channel to Channel Load 1.2V Turn-On Characteristic Isolation VOUT2 to VOUT1 Isolation VOUT1 to VOUT2
