matched differential amplifier output calculator online

Use matched differential amplifier output online for ratio, input1 V, input2 V. Requires matched resistor ratios; input common-mode limits excluded. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter ratio. Set input1 V, input2 V. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
ratioMain input. Positive values. 10
input1 VOption. Signed finite values. 0.2
input2 VOption. Signed finite values. 0.3

Calculation method

output_V = ratio*(input2_V-input1_V) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply matched differential amplifier output to the case below, keeping the displayed units and assumptions. Requires matched resistor ratios; input common-mode limits excluded.

Choose the right tool

Match the topology before entering values: series and parallel networks, inverting and noninverting stages, and buck and boost converters use different equations. Component ratings, parasitics, protection and measured conditions require separate review.

Limitations and common mistakes

  • Requires matched resistor ratios; input common-mode limits excluded. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
