**VCIS for Floating Load – Examples**

**Example D1:**

a. Determine load current (assuming linear operation)

b. Determine \(V_{\text{out}}\) for the loads in the table

c. Determine the max load

---

**Parameters:**

- **\(V_{\text{sig}}\):** 3 V
- **\(V_{cc}/-V_{cc}\):** 12V / -12V (Ideal rails)

---

**Circuit Diagram:**

- An operational amplifier (op-amp) is connected with \(V_{\text{sig}}\) input.
- The output is connected to a load.
- A resistor \(R1 = 1k\) is connected to ground, and the current through it is labeled \(I_{\text{LOAD}}\).

---

**Load Table:**

| Load  | \(V_{\text{out}}\) (Ideal) | \(V_{\text{out}}\) (Actual) |
|-------|-----------------------|------------------------|
| 1k    |                       |                        |
| 2k    |                       |                        |
| 8k    |                       |                        | 

---

In this example, you are tasked with calculating the load current, the ideal and actual output voltages for different load resistances, and determining the maximum possible load. The table provides three different load resistances: 1k, 2k, and 8k, and you need to fill in the corresponding \(V_{\text{out}}\) values.
