Your goal is to create a 3.3 V, 20 dB amplifier schematic in this project.

I’ve prepared the plan.
It will:
1. Set up the supply and enable path
2. Configure the gain network for 20 dB
3. Add required support parts and connections
4. Review the schematic for completeness

Click Start on the plan bar to run it. Let me know if you want any requirement changed first.

Plan

#Goal

Create the schematic for the ADA4841-1 op amp project configured for 20 dB gain and operating from a 3.3 V low dropout (LDO) power supply.

#Implementation plan

Power Supply Setup
1. Add and configure a 3.3 V LDO regulator to supply power for the op amp.
2. Connect and ground the LDO output to the ADA4841-1 positive power terminal.
Op Amp Configuration
1. Place the ADA4841-1 op amp from the parts library and configure its supply connections for 3.3 V single-supply operation.
2. Determine and add the necessary resistors to set 20 dB gain. For 20 dB (gain=10), calculate resistor network values (e.g., Rf and Rin) and add them to the circuit.
3. Connect the resistors between the op amp outputs, inverting input, and non-inverting input as required to realize the 20 dB amplifier configuration.
Signal Interface and Support
1. Connect the amplifier inputs and outputs to schematic terminals for proper interfacing (terminal labels OUTPUT, +, -, etc.).
2. Review and ensure proper grounding and decoupling around the op amp and LDO for stability.
Schematic Review
1. Validate all component connections follow the 3.3 V single-supply design and 20 dB gain requirement.
2. Verify that connections between the power supply, op amp, and resistor network are correct.

#Success criteria

ADA4841-1 op amp is correctly powered from a 3.3 V LDO with proper decoupling elements.
The resistor network accurately sets a closed-loop gain of 20 dB for the op amp.
Schematic terminals (OUTPUT, V-, ~PD, +, -, and V+) are correctly connected and labelled for further layout and simulation steps.
