OPA4313IPWR

Texas Instruments · Operational Amplifier · TSSOP-14

OPA4313IPWR from Texas Instruments, in a TSSOP-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 OUT A output Channel A output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and the datasheet specifies a short-circuit current of ±15 mA at VS=5.5 V.
2 -IN A input Channel A inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, and input current should be limited to 10 mA when the input is driven beyond a supply rail by more than 0.5 V.
3 +IN A input Channel A non-inverting input has a common-mode range that extends about 200 mV beyond both supply rails, with CMRR, PSRR, offset and THD possibly degrading in the crossover region near (V+)-1.3 V.
4 V+ power_in Positive supply, rated 1.8 V to 5.5 V (±0.9 V to ±2.75 V), and the datasheet recommends bypassing it with a 0.01 µF ceramic capacitor.
5 +IN B input Channel B non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails.
6 -IN B input Channel B inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail.
7 OUT B output Channel B output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V.
8 OUT C output Channel C output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V.
9 -IN C input Channel C inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail.
10 +IN C input Channel C non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails.
11 V- power_in Negative supply rail, used as ground in single-supply operation, to which all input and output voltage limits are referenced.
12 +IN D input Channel D non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails.
13 -IN D input Channel D inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail.
14 OUT D output Channel D output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V.
