AD8016t5 Power-Down Op Amp Enabled Non-Inverting Amplifier

Application

This circuit shows AD8016t5 operating as a normal non-inverting gain stage while its power-down control pins are held in the enabled state. It is intended as a clear starting point before experimenting with low-power control behavior.

Design Context

Vin drives the non-inverting input through the switch. RF and RG set a nominal gain of 2, the output drives a resistive and LED load, and the split supplies provide ample headroom. PWDN0 and PWDN1 are tied to the return rail so the amplifier remains active in this application circuit.

Expected Behavior

Vout should follow Vin with approximately 2x gain while the output load current remains modest. The power-down pins should not be floating; tying them to the enabled state makes the amplifier behavior easy to compare with other op amp demos.

Key Values

• Vin: 1 V AC source through the switch.
• RF and RG: 1K each for nominal 2x non-inverting gain.
• PWDN0 and PWDN1: tied to return for enabled operation.
• Supplies: +15 V and -15 V.

Suggested Experiments

• Toggle the input switch and compare Vin and Vout.
• Change RF or RG to adjust closed-loop gain.
• Rewire the power-down controls to evaluate disabled-state behavior in a separate copy.

Featured Component

AD8016t5 Power-Down Op Amp is the featured seven-pin op amp; the demo keeps its control pins visible and intentionally biased.
