LMH6505MAX

Texas Instruments · Programmable / Variable Gain Amplifiers (PGA/VGA) · SOIC-8

LMH6505MAX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

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
