LM13700M from HGSEMI, in a SOP-16. 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 the transconductance gm of amplifier A; typical operating range is a few µA up to 500 µA, absolute max 2 mA. Internally sits two Vbe above V-.
2 Diode Bias A input Linearizing diode bias current input for channel A. Supplying a bias current (typ. 1 mA, max 2 mA) through the internal input diodes reduces distortion and extends usable differential input voltage range. Leave floating if diode linearization is not used.
3 Input+ A input Non-inverting differential input of amplifier A. Max differential input voltage ±5 V; input common-mode range typ. ±13.5 V with ±15 V supplies.
4 Input- A input Inverting differential input of amplifier A. Max differential input voltage ±5 V; input impedance typ. 26 kΩ.
5 Output A output Unbuffered current output of transconductance amplifier A. Output current is IABC * tanh(Vin*q/2kT); peak output current tracks IABC (typ. 500 µA at IABC=500 µA). Continuous short-circuit to ground is allowed.
6 V- power_in Negative supply rail. Single-supply operation 9.5 V to 32 V; split-supply operation -4.75 V to -16 V (absolute max ±18 V, 36 V total). Shared by both amplifier channels.
7 Buffer Input A input High-impedance input of Darlington output buffer for channel A. Typical input bias current 0.5 µA; independent of IABC, unlike the LM13600.
8 Buffer Output A output Emitter-follower Darlington buffer output for channel A. Drives up to 20 mA; peak output voltage swing typ. 10 V. Requires an external pull-down resistor to V-.
9 Buffer Output B output Emitter-follower Darlington buffer output for channel B. Drives up to 20 mA; peak output voltage swing typ. 10 V. Requires an external pull-down resistor to V-.
10 Buffer Input B input High-impedance input of Darlington output buffer for channel B. Typical input bias current 0.5 µA; independent of IABC.
11 V+ power_in Positive supply rail. Single-supply operation 9.5 V to 32 V; split-supply operation +4.75 V to +16 V (absolute max ±18 V, 36 V total). Shared by both amplifier channels.
12 Output B output Unbuffered current output of transconductance amplifier B. Output current tracks IABC; peak output current typ. 500 µA at IABC=500 µA. Continuous short-circuit to ground is allowed.
13 Input- B input Inverting differential input of amplifier B. Max differential input voltage ±5 V; input impedance typ. 26 kΩ.
14 Input+ B input Non-inverting differential input of amplifier B. Max differential input voltage ±5 V; input common-mode range typ. ±13.5 V with ±15 V supplies.
15 Diode Bias B input Linearizing diode bias current input for channel B. Supplying a bias current (typ. 1 mA, max 2 mA) through the internal input diodes reduces distortion. Leave floating if diode linearization is not used.
16 Amp Bias Input B input Amplifier bias current (IABC) input for channel B. Sets the transconductance gm of amplifier B; typical operating range is a few µA up to 500 µA, absolute max 2 mA.
