ADA4899-1YRDZ
Analog Devices · Operational Amplifier · SOIC-8-EP
ADA4899-1YRDZ 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 | input | Dedicated feedback pin on the opposite side of the package, intended to connect the feedback network to the inverting input and isolate the output-pin capacitive load and package inductance from the feedback loop. |
| 2 | -IN | input | Inverting input; the internal antiparallel diodes limit the differential input voltage to approximately ±1.2 V, and the input common-mode range is −3.7 V to +3.7 V with ±5 V supplies. |
| 3 | +IN | input | Noninverting input; the input common-mode voltage range is −3.7 V to +3.7 V with ±5 V supplies and 1.3 V to 3.7 V with a +5 V supply. |
| 4 | -VS | power_in | Negative supply pin, one of two negative supply pins on the SOIC; the total supply range is 4.5 V to 12 V and the absolute maximum supply voltage is 12.6 V. |
| 5 | -VS | power_in | Second negative supply pin, provided so the SOIC supports both an input-isolated layout and a traditional SOIC board layout. |
| 6 | VOUT | output | Amplifier output; output swing is −3.7 V to +3.7 V with RL = 1 kΩ and −3.25 V to +3.25 V with RL = 100 Ω at ±5 V, with short-circuit current of 160/200 mA sinking/sourcing. |
| 7 | +VS | power_in | Positive supply pin; the operating range is 4.5 V to 12 V and the absolute maximum supply voltage is 12.6 V. |
| 8 | DISABLE | input | Three-state disable input: pulling it low (−5 V to +2.4 V at ±5 V supply) places the output in a high-impedance state, leaving it open enables normal operation, and pulling it within 0.7 V of +VS turns on the low input bias current mode. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
