# OPA2354AIDDAR

**Texas Instruments** · Operational Amplifier · HSOP-8-EP

OPA2354AIDDAR from Texas Instruments, in a HSOP-8-EP. 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 | Output of channel A; the 8-pin HSOIC PowerPAD version is the one specified for full 100 mA continuous output current, and output short-to-ground is continuous per the absolute maximum ratings. |
| 2 | -IN A | input | Inverting input of channel A; signal input terminals are limited to (V-) - 0.5 V to (V+) + 0.5 V and ±10 mA input current. |
| 3 | +IN A | input | Non-inverting input of channel A; the common-mode input range extends from (V-) - 0.1 V to (V+) + 0.1 V. |
| 4 | V- | power_in | Negative (lowest) power supply; total supply VS = (V+) - (V-) is recommended at 2.5 V to 5.5 V and absolute maximum is 7.5 V, and the thermal pad must be connected to V- or left floating. |
| 5 | +IN B | input | Non-inverting input of channel B; the common-mode input range extends from (V-) - 0.1 V to (V+) + 0.1 V. |
| 6 | -IN B | input | Inverting input of channel B; signal input terminals are limited to (V-) - 0.5 V to (V+) + 0.5 V and ±10 mA input current. |
| 7 | OUT B | output | Output of channel B; the 8-pin HSOIC PowerPAD version is the one specified for full 100 mA continuous output current, and output short-to-ground is continuous per the absolute maximum ratings. |
| 8 | V+ | power_in | Positive (highest) power supply; with V- it sets the recommended total supply of 2.5 V to 5.5 V, with an absolute maximum of 7.5 V. |
| 9 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
