INA163UA

Texas Instruments · Instrumentation Amplifiers · SOIC-14

INA163UA 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 VO1 output Output terminal 1 from internal instrumentation amplifier circuit
2 NC unconnected No internal connection
3 GS1 passive Gain-setting resistor terminal; external resistor RG connects between pins 3 and 12 to set gain as G = 1 + 6000/RG
4 VIN− power_in Negative differential input signal terminal; input signal voltage range (V−)−0.5V to (V+)+0.5V with maximum current of 10mA
5 VIN+ power_in Positive differential input signal terminal; input signal voltage range (V−)−0.5V to (V+)+0.5V with maximum current of 10mA
6 V− power_in Negative power supply rail; operating voltage range ±4.5V to ±18V
7 NC unconnected No internal connection
8 Sense output Output sense terminal for feedback loop compensation; low-impedance connection to load maintains common-mode rejection ratio greater than 100dB
9 VO output Primary output signal terminal with voltage swing (V+)−2 to (V+)−1.8 volts and (V−)+2 to (V−)+1.8 volts into 2kΩ load; maximum short-circuit current ±60mA continuous to ground
10 Ref input Reference voltage input terminal; externally applied voltage is summed with the output signal for offset voltage adjustment
11 V+ power_in Positive power supply rail; operating voltage range ±4.5V to ±18V
12 GS2 passive Gain-setting resistor terminal; external resistor RG connects between pins 3 and 12 to set gain as G = 1 + 6000/RG
13 NC unconnected No internal connection
14 VO2 output Output terminal 2 from internal instrumentation amplifier circuit
