<opamp />

Overview

An <opamp /> represents an operational amplifier. It is useful for analog circuits such as gain stages, filters, and signal conditioning blocks.

The element includes the standard op-amp connections for the inverting input, non-inverting input, output, and power pins.

For parts with unusual pinouts or extra control pins, prefer <chip />.

export default () => (
<board width="10mm" height="10mm">
  <net name="VCC" isPowerNet />
  <net name="VEE" isGroundNet />

  <opamp
    name="U1"
    footprint="soic8"
    connections={{
      non_inverting_input: "net.IN_POS",
      inverting_input: "net.IN_NEG",
      output: "net.OUT",
      positive_supply: "net.VCC",
      negative_supply: "net.VEE",
    }}
  />
</board>
)

In this example, the op-amp is placed on a board and connected to named input, output, and supply nets.

Properties

Property	Description	Example
connections	Net connections for the standard op-amp pins.	{ output: "net.OUT" }
footprint	PCB footprint string or custom footprint.	"soic8"
symbolName	Override the default schematic symbol name.	"opamp_with_power"

Pins

An op-amp has the following pins and aliases:

• pin1/non_inverting_input - The non-inverting input
• pin2/inverting_input - The inverting input
• pin3 or pin4/output - The output pin
• pin4 or pin5/positive_supply/vcc/vdd - The positive supply pin
• pin5 or pin3/negative_supply/vee/vss/gnd - The negative supply pin

If you need a different pinout, multiple amplifier channels in one package, or extra enable/offset pins, use <chip /> with explicit pinLabels.
