Within the Ca3080e datasheet, you will typically find application circuits illustrating how the CA3080E can be used in different scenarios. These example circuits provide starting points for designing your own circuits and demonstrate the versatility of the OTA. Common applications include:
- Voltage-controlled amplifiers (VCAs)
- Electronic gain control circuits
- Amplitude modulators
- Active filters
The importance of consulting the Ca3080e datasheet is particularly evident when dealing with parameters like transconductance (gm), which is the ratio of output current to input voltage. This parameter is at the heart of how OTAs operate and understanding its relationship with the bias current (IABC) is critical. The datasheet usually provides a graph or formula showing how gm varies with IABC. For example, it may show that increasing the bias current increases the transconductance, leading to higher gain. Here’s a simple representation of what you might find in the datasheet concerning bias current:
| Parameter | Typical Value |
|---|---|
| Bias Current (IABC) | 1 mA |
| Transconductance (gm) | 19.2 mS |
