LMH6503MAX

Texas Instruments · Programmable / Variable Gain Amplifiers (PGA/VGA) · SOIC-14

LMH6503MAX from Texas Instruments, in a SOIC-14. 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 V+ power_in Positive supply pin; the datasheet characterizes the part at VS = ±5V.
2 VG input Gain control voltage input with high input impedance (70kΩ, 1.3pF); gain control range is −1V to +1V relative to the GND pin (pin 11).
3 +VIN input Non-inverting differential input (pins 3 and 6 share a ±2.0V minimum common-mode input range, 750kΩ input resistance, 5pF input capacitance); the unused input can be tied to ground for single-ended operation.
4 +RG passive Gain-setting resistor RG connection (pins 4 and 5), with maximum RG current of ±1.70mA minimum.
5 -RG passive Gain-setting resistor RG connection (pins 4 and 5), with maximum RG current of ±1.70mA minimum.
6 -VIN input Inverting differential input (pins 3 and 6 have 11µA typical bias current and ±0.34V minimum differential input voltage across them).
7 V- power_in Negative supply pin; the datasheet characterizes the part at VS = ±5V.
8 V- power_in Negative supply pin; the datasheet characterizes the part at VS = ±5V.
9 VREF power_in Reference pin of the output stage as labeled in the connection diagram; the datasheet text provided gives no further limits.
10 VOUT output Output of the current feedback op amp, able to drive ±3.2V typical into 100Ω with ±75mA minimum output current.
11 GND power_in Ground pin, the reference potential for the −1V to +1V gain control range; tied to a virtual half supply in single-supply operation.
12 I- input Inverting input of the output current feedback op amp as labeled in the connection diagram; the datasheet text provided gives no further limits.
13 NC unconnected No connect pin.
14 V+ power_in Positive supply pin; the datasheet characterizes the part at VS = ±5V.
