Iint min (IL = 6mA) = 4 /56K + 60 = 130µA

Iint min (IL = ILb) = 8 /56K + 60 = 200µA

Vpin17 = 2.5V ⇒ R6 = 18KΩ ⇒

Vpin16 min (IL = 6mA) = 2.5 + 18 • 130E - 3 = 4.85V

Vpin16 max (IL = ILb) = 2.5 + 18 • 200E - 3 = 6.1V

♦ Current Sources

Iup min (IL = 6mA) = 0.5mA

Iup max (IL = ILb) = 2.5mA

Iear min (IL = 6mA) = 0.55mA

Iear max (IL = ILb) = 7.5mA

with RZ = 75Ω

Itr min (IL = 6mA) = 2.35mA

Itr max (IL = ILb) = 4.5mA

ILS min (IL = 6mA) = 1.17mA

ILb = 22.4mA

ILS (for IL = ILb) = 0.285 • ILb = 6.4mA

♦ at IL = 100mA:

∆(ILS) = 0.91 • ∆(IL) = 0.91 • (100 - 22.6) = 64mA

ILS = 6.4 + 64 = 70.4mA
