OPA2350EA

Texas Instruments · Operational Amplifier · VSSOP-8

OPA2350EA from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT_A output Output of channel A. Class-AB rail-to-rail output stage; swings to within ~10 mV of the supply rails with a 10-kΩ load. Short-circuit current ±80 mA typical; continuous output current ±40 mA typical.
2 -IN_A input Inverting input of channel A. High-impedance CMOS gate input (10^13 Ω differential, ~13 pF common-mode). Input bias current ±0.5 pA typical. Input common-mode range: (V-) - 0.1 V to (V+) + 0.1 V.
3 +IN_A input Noninverting input of channel A. High-impedance CMOS gate input (10^13 Ω differential, ~13 pF common-mode). Complementary N/P input pair supports rail-to-rail common-mode operation. Diode-clamped to supply rails; limit external current to 10 mA if driven beyond rails.
4 V- power_in Negative power supply (or ground for single-supply operation). Total supply (V+) - (V-) range 2.7 V to 5.5 V (specified), 2.5 V to 5.5 V operational. Bypass to V+ (or GND) with a low-ESR 0.1-µF ceramic capacitor placed close to the pin.
5 +IN_B input Noninverting input of channel B. High-impedance CMOS gate input with rail-to-rail common-mode range extending 100 mV beyond each supply rail. Diode-clamped to the supplies; keep current below 10 mA for over-range signals.
6 -IN_B input Inverting input of channel B. High-impedance CMOS gate input (10^13 Ω differential). Input offset current ±0.5 pA typical. Channel B is fully independent of channel A for low crosstalk.
7 OUT_B output Output of channel B. Class-AB rail-to-rail output stage capable of driving 600-Ω loads. Short-circuit current ±80 mA typical; open-loop gain 122 dB typical at RL = 10 kΩ.
8 V+ power_in Positive power supply. 2.7 V to 5.5 V specified (2.5 V to 5.5 V operational) relative to V-. Quiescent current 5.2 mA per amplifier typical (10.4 mA total for the dual). Bypass to V- (or GND) with a 0.1-µF low-ESR ceramic capacitor located close to the pin.
