# OPA2300AIDGSR

**Texas Instruments** · Operational Amplifier · VSSOP-10-0.5mm

OPA2300AIDGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 | OutA | output | Channel A output voltage; the datasheet gives no numeric output limit for this pin, and output swings to within about 100mV of the supply rails at high load (>2kΩ). |
| 2 | -InA | input | Channel A negative (inverting) input voltage. |
| 3 | +InA | input | Channel A positive (non-inverting) input voltage; input voltages more than 0.5V beyond the supply rails must be limited to 10mA or less. |
| 4 | V- | power_in | Negative power supply voltage; the operating supply range is 2.7V to 5.5V total (V+ minus V-). |
| 5 | EnableA | input | Channel A enable pin, referenced to V-: logic high (at least V- + 2.5V) enables the amplifier, logic low (below V- + 0.8V) disables it, and a floating pin is pulled high by internal circuitry. |
| 6 | EnableB | input | Channel B enable pin, referenced to V-: logic high (at least V- + 2.5V) enables the amplifier, logic low (below V- + 0.8V) disables it, and a floating pin is pulled high by internal circuitry. |
| 7 | +InB | input | Channel B positive (non-inverting) input voltage; input voltages more than 0.5V beyond the supply rails must be limited to 10mA or less. |
| 8 | -InB | input | Channel B negative (inverting) input voltage. |
| 9 | OutB | output | Channel B output voltage; the datasheet gives no numeric output limit for this pin, and output swings to within about 100mV of the supply rails at high load (>2kΩ). |
| 10 | V+ | power_in | Positive power supply voltage; the operating supply range is 2.7V to 5.5V total (V+ minus V-), with 5.5V as the absolute maximum. |
