ADA4899-1YRDZ-R7 from Analog Devices, in a SOIC-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 | FEEDBACK | passive | Dedicated feedback pin connected internally to the output, placed on the opposite side of the package from the inverting input to ease connecting the feedback network to -IN. |
| 2 | -IN | input | Inverting input; differential input voltage is limited to ±1.2 V and ±10 mA by internal protection diodes. |
| 3 | +IN | input | Noninverting input; differential input voltage is limited to ±1.2 V and ±10 mA by internal protection diodes. |
| 4 | -VS | power_in | Negative supply pin, isolated from the inputs for low second harmonic distortion; operating supply range is 4.5 V to 12 V total. |
| 5 | -VS | power_in | Second negative supply pin (unused pin 5 of the standard SOIC pinout), allowing either an input-isolated or a traditional board layout. |
| 6 | VOUT | output | Amplifier output, which drives 100 Ω loads and has a short-circuit current of 160/200 mA sinking/sourcing at ±5 V. |
| 7 | +VS | power_in | Positive supply pin; operating supply range is 4.5 V to 12 V, with 12.6 V absolute maximum. |
| 8 | DISABLE | input | Three-state input: pulling it low (below 2.4 V for ±5 V supply) disables the output, floating gives normal operation, and pulling it within 0.7 V of +VS (4.3 V to 5 V) enables input bias current cancellation. |
| 9 | EPAD | passive | Exposed pad on the bottom of the package, which must be soldered to the ground plane for electrical and thermal performance. |
