For each op-amp in Figure P14.50, the input bias current is \(I_{B}=500 \mathrm{nA}\) at \(T=25^{\circ} \mathrm{C}\), the input offset current is \(I_{O S}=200 \mathrm{nA}\) at \(T=25^{\circ} \mathrm{C}\), the input bias current temperature coefficient is \(8 \mathrm{nA} /{ }^{\circ} \mathrm{C}\), and the input offset current temperature coefficient is \(2 \mathrm{nA} /{ }^{\circ} \mathrm{C}\).

(a) Find the output voltage due to the average input bias currents at \(T=25^{\circ} \mathrm{C}\).

(b) Find the worst-case output voltage due to the input bias current and input offset current at \(T=25^{\circ} \mathrm{C}\).

(c) Repeat parts (a) and (b) for \(T=50^{\circ} \mathrm{C}\).
