Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VG | input | Gain control input voltage, 0V to 2V range sets VGA gain from approximately -85dB to +9.4dB; input impedance 25MΩ, bias current 0.9µA typical |
| 2 | VIN | input | Inverting signal input with input voltage range ±0.6V to ±0.74V with RG=100Ω; input impedance 7MΩ, bias current ±2.5µA typical |
| 3 | RG | input | Gain setting resistor connection for external resistor, external resistor from VIN to GND sets gain with RF feedback resistor; maximum pin current ±7.4mA |
| 4 | GND | power_in | Ground reference pin providing 0V reference for all signal and supply voltage levels |
| 5 | V+ | power_in | Positive power supply voltage, typical +5V, total supply range 7V to 12V, supply current 11mA typical at no load |
| 6 | VOUT | output | Output signal voltage with swing ±2.4V typical into 100Ω load, output impedance 0.12Ω DC, maximum output current ±60mA |
| 7 | V- | power_in | Negative power supply voltage, typical -5V, total supply range 7V to 12V |
| 8 | X1 | unconnected | No internal connection |
