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. |
