**Texas Instruments** · Operational Amplifier · PDIP-8

MC1458P from Texas Instruments, in a PDIP-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 | 1OUT | output | Output of amplifier 1. Short-circuit protected; can drive loads down to 2 kOhm with typical +/-13 V swing at VCC = +/-15 V. Output resistance ~75 Ohm; short-circuit output current typ +/-25 mA. |
| 2 | 1IN- | input | Inverting input of amplifier 1. High-impedance input (typ 2 MOhm); input bias current typ 80 nA, input offset current typ 20 nA. Must not exceed |VI| = 15 V or the supply magnitude. |
| 3 | 1IN+ | input | Non-inverting input of amplifier 1. Common-mode input voltage range typ +/-13 V at VCC = +/-15 V. Differential input voltage rating +/-30 V absolute max. |
| 4 | VCC- | power_in | Negative supply rail. Absolute max -18 V for MC1458; recommended operating -5 V to -15 V. Shared by both amplifiers. |
| 5 | 2IN+ | input | Non-inverting input of amplifier 2. Common-mode input voltage range typ +/-13 V at VCC = +/-15 V. Differential input voltage rating +/-30 V absolute max. |
| 6 | 2IN- | input | Inverting input of amplifier 2. High-impedance input (typ 2 MOhm); input bias current typ 80 nA, input offset current typ 20 nA. Must not exceed |VI| = 15 V or the supply magnitude. |
| 7 | 2OUT | output | Output of amplifier 2. Short-circuit protected; can drive loads down to 2 kOhm with typical +/-13 V swing at VCC = +/-15 V. Output resistance ~75 Ohm; short-circuit output current typ +/-25 mA. |
| 8 | VCC+ | power_in | Positive supply rail. Absolute max +18 V for MC1458; recommended operating +5 V to +15 V. Supply current typ 3.4 mA (both amplifiers) at VO = 0, no load. |
