HT741ARZ from HTCSEMI, in a SOP-8. 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 | OFFSET_NULL | input | Offset null pin used with pin 5 and an external trim potentiometer (typ. 10 kΩ to V-) to eliminate the input offset voltage and balance the input stage. |
| 2 | INVERTING_INPUT | input | Inverting signal input (-) of the operational amplifier. Input common-mode range ±12 V (typ) at Vcc = ±15 V. |
| 3 | NONINVERTING_INPUT | input | Non-inverting signal input (+) of the operational amplifier. Input common-mode range ±12 V (typ) at Vcc = ±15 V. |
| 4 | V- | power_in | Negative supply voltage. Operating range ±5 V to ±18 V (absolute maximum ±20 V). Typical quiescent supply current 2.8 mA. |
| 5 | OFFSET_NULL | input | Offset null pin used with pin 1 and an external trim potentiometer (wiper to V-) to eliminate the input offset voltage. |
| 6 | OUTPUT | output | Amplified signal output. Output swing typ. ±12 V into 10 kΩ, ±10 V into 2 kΩ; short-circuit current typ. 10 mA; slew rate typ. 0.25 V/µs. |
| 7 | V+ | power_in | Positive supply voltage. Operating range ±5 V to ±18 V (absolute maximum ±20 V). Typical quiescent supply current 2.8 mA. |
| 8 | NC | unconnected | No connect. Should be left floating. |
