## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-op-amp-gain-calculator-473a0f2f
```

Example prompt: What standard E96 resistors should I use for a non-inverting op-amp with a gain of 20, using a 1MHz GBW op-amp, 1% tolerance, and a 5V supply rail?

## When to prefer this

Use this endpoint when you need to pick real, purchasable standard-value resistors (E24 or E96 series) for an op-amp gain stage rather than computing ideal theoretical values. It is especially useful when you want to verify bandwidth and slew-rate constraints, check for output clipping, and understand the tolerance spread on your actual gain — all in one call. Prefer it over manual calculation when designing inverting, non-inverting, or difference amplifier configurations with practical component constraints.

## Known failure modes

- Missing required parameters 'config' or 'gain' returns a 400 error
- Invalid config value (not inverting, non_inverting, or difference) causes a validation error
- Gain value outside achievable range with given resistor constraints returns no valid solution
- rf_min_ohm greater than rf_max_ohm causes a constraint conflict error
- Non-numeric string values for numeric parameters may return a parse error
- Very high gain targets with narrow resistor range may yield no standard-value solution

## How this service works

Standard-value resistors for target gain, bandwidth, slew limit and tolerance spread

## Output

A JSON object containing the recommended standard-value resistors (e.g. Rf and Rg values from the chosen E-series), the resulting actual gain, the bandwidth limit based on the op-amp GBW, the slew-rate frequency limit, the worst-case gain spread due to resistor tolerance, and optionally a clipping warning if the input peak voltage would saturate the output given the supply rail.
