onsemi · Precision Op Amps · SOIC-14

NCS21914DR2G from onsemi, in a SOIC-14. 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 OUT1 output Amplifier 1 output. Rail-to-rail output stage, swings within ~10 mV of the supply rails; short-circuit current typ. 16 mA sourcing / 18 mA sinking; drives up to 1 nF capacitive load.
2 IN-1 input Amplifier 1 inverting input. High-impedance CMOS input; input bias current typ. ±100 pA; input diode-clamped to supply rails through 1.65 kΩ (limit input current to ±10 mA).
3 IN+1 input Amplifier 1 non-inverting input. Common-mode range VSS to VDD-1.5 V; CMRR typ. 150 dB at VS = 36 V; ESD/latch-up protected inputs.
4 VDD power_in Positive supply pin, shared by all four amplifiers. Operating range 4 V to 36 V (VDD-VSS ≤ 40 V absolute max). Quiescent current typ. 475 µA / max 570 µA per channel. Bypass with a local 0.1 µF ceramic close to the pin.
5 IN+2 input Amplifier 2 non-inverting input. Common-mode range VSS to VDD-1.5 V; input impedance is very high (CMOS gate).
6 IN-2 input Amplifier 2 inverting input. High-impedance input; differential input voltage limited to ±17 V by internal clamp diodes with 1.65 kΩ series protection.
7 OUT2 output Amplifier 2 output. Rail-to-rail; VOH/VOL typ. 100 mV from rail with 10 kΩ load; slew rate typ. 1.6 V/µs.
8 OUT3 output Amplifier 3 output. Rail-to-rail output; short-circuit protected; drives up to 1 nF cap load.
9 IN-3 input Amplifier 3 inverting input. High-impedance CMOS input; internal input protection diodes to VDD/VSS with 1.65 kΩ series (limit external input current to ±10 mA).
10 IN+3 input Amplifier 3 non-inverting input. Common-mode range VSS to VDD-1.5 V.
11 VSS power_in Negative supply / ground pin, shared by all four amplifiers. Total supply (VDD-VSS) 4 V to 36 V operating, 40 V absolute max. In single-supply designs tie to GND.
12 IN+4 input Amplifier 4 non-inverting input. Common-mode range VSS to VDD-1.5 V; CMOS high-impedance input.
13 IN-4 input Amplifier 4 inverting input. High-impedance input; internal ESD/latch-up protection.
14 OUT4 output Amplifier 4 output. Rail-to-rail; open-loop gain typ. 150 dB; output impedance behavior per Figure 23.
