Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | AMP_BIAS_INPUT_A | input | Amplifier bias current (IABC) input for channel A. Sets forward transconductance gm; recommended IABC up to 2 mA max. Typical gm ≈ 9600 μS at IABC = 500 μA. |+| 2 | DIODE_BIAS_A | input | Linearizing diode bias input for channel A. Injecting ID (max 2 mA) forward-biases the internal diode pair to reduce distortion at higher input levels. |+| 3 | IN+_A | input | Non-inverting (positive) differential input of transconductance amplifier A. Common-mode range ±13.5 V typ at ±15 V supplies; differential input voltage ±5 V max. |+| 4 | IN-_A | input | Inverting (negative) differential input of transconductance amplifier A. Same electrical limits as IN+. |+| 5 | OUT_A | output | Unbuffered current output of transconductance amplifier A. IOUT = gm · Vdiff; peak output current typ 500 μA at IABC = 500 μA. Usually fed to buffer input (pin 7). |+| 6 | V- | power_in | Negative supply. Dual-supply range −16 V to −4.75 V; total supply voltage up to 36 VDC (or ±18 V). Shared by both channels. |+| 7 | BUF_IN_A | input | Darlington buffer amplifier input for channel A. Typical buffer input bias current 0.5 μA (2 μA max). High-impedance buffer input, typically tied to OUT_A. |+| 8 | BUF_OUT_A | output | Darlington buffer amplifier output for channel A. Peak buffer output voltage typ 10 V; buffer output current limited to 20 mA absolute maximum. |+| 9 | BUF_OUT_B | output | Darlington buffer amplifier output for channel B. Peak buffer output voltage typ 10 V; buffer output current limited to 20 mA absolute maximum. |+| 10 | BUF_IN_B | input | Darlington buffer amplifier input for channel B. Typical buffer input bias current 0.5 μA (2 μA max). High-impedance buffer input, typically tied to OUT_B. |+| 11 | V+ | power_in | Positive supply. Single-supply range 9.5 V to 32 V; dual-supply range 4.75 V to 16 V. Shared by both channels. |+| 12 | OUT_B | output | Unbuffered current output of transconductance amplifier B. IOUT = gm · Vdiff; peak output current typ 500 μA at IABC = 500 μA. |+| 13 | IN-_B | input | Inverting (negative) differential input of transconductance amplifier B. Differential input voltage ±5 V max; DC input voltage clamped between +Vs and −Vs. |+| 14 | IN+_B | input | Non-inverting (positive) differential input of transconductance amplifier B. Common-mode range ±13.5 V typ at ±15 V supplies. |+| 15 | DIODE_BIAS_B | input | Linearizing diode bias input for channel B.
