AD8476ACPZ-R7 from Analog Devices, in a LFCSP-16(3x3). 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 | INP | input | Positive input; the differential input range is −VS + 0.05 V to +VS − 0.05 V, and the ESD protection diodes protect the input up to +VS + 18 V. |
| 2 | INP | input | Positive input; the differential input range is −VS + 0.05 V to +VS − 0.05 V, and the ESD protection diodes protect the input up to +VS + 18 V. |
| 3 | INN | input | Negative input; the differential input range is −VS + 0.05 V to +VS − 0.05 V, and the ESD protection diodes protect the input up to −VS − 18 V. |
| 4 | INN | input | Negative input; the differential input range is −VS + 0.05 V to +VS − 0.05 V, and the ESD protection diodes protect the input up to −VS − 18 V. |
| 5 | +VS | power_in | Positive supply; single supply range is 3 V to 18 V, or dual supplies ±1.5 V to ±9 V, with absolute maximum supply voltage ±10 V. |
| 6 | +VS | power_in | Positive supply; single supply range is 3 V to 18 V, or dual supplies ±1.5 V to ±9 V, with absolute maximum supply voltage ±10 V. |
| 7 | +VS | power_in | Positive supply; single supply range is 3 V to 18 V, or dual supplies ±1.5 V to ±9 V, with absolute maximum supply voltage ±10 V. |
| 8 | +VS | power_in | Positive supply; single supply range is 3 V to 18 V, or dual supplies ±1.5 V to ±9 V, with absolute maximum supply voltage ±10 V. |
| 9 | VOCM | input | Output common-mode adjust; the VOCM input voltage range is −VS + 1 V to +VS − 1 V with 500 kΩ input impedance, and the pin can be left unconnected to self-bias the output to midsupply. |
| 10 | +OUT | output | Noninverting output with rail-to-rail swing, specified for up to 20 pF capacitive load per output and a 35 mA short-circuit current limit. |
| 11 | −OUT | output | Inverting output with rail-to-rail swing, specified for up to 20 pF capacitive load per output and a 35 mA short-circuit current limit. |
| 12 | NC | unconnected | Not connected internally; it may be left floating but is better connected to ground, and high-speed signals should be kept off it to avoid noise coupling. |
| 13 | −VS | power_in | Negative supply; part of the negative supply connection for the single or dual supply range given for +VS. |
| 14 | −VS | power_in | Negative supply; part of the negative supply connection for the single or dual supply range given for +VS. |
| 15 | −VS | power_in | Negative supply; part of the negative supply connection for the single or dual supply range given for +VS. |
| 16 | −VS | power_in | Negative supply; part of the negative supply connection for the single or dual supply range given for +VS. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
