Substitutes same socket
Parts that fit the same socket: the same function, pin count and pinout. The figures are read off each part's datasheet (this one's from page 3), typical where the sheet gives a typical value, otherwise the maximum. Closest first; the last column says what differs. A different part can change the sound, and a circuit may lean on one particular figure, so read the build document's notes before you swap.
This part
| Part | Input | Supply | GBW | Slew | Noise | Iq | Boards |
|---|---|---|---|---|---|---|---|
| LM4562 | bipolar | 5–34 V | 55 MHz | 20 V/µs | 2.7 nV | 5 mA | 8 |
Very low noise and distortion, but 55 MHz GBW and 10 mA total supply current; needs a tight layout and decoupling.
Fits the same socket
| Part | Input | Supply | GBW | Slew | Noise | Iq | Boards | Differs |
|---|---|---|---|---|---|---|---|---|
| UPC4570 | bipolar | 8–32 V | 15 MHz | 7 V/µs | 2.5 mA | 5 | Low-noise, wideband audio dual; needs at least ±4 V (8 V) supply. | |
| LM833 | bipolar | 10–36 V | 16 MHz | 7 V/µs | 4.5 nV | 2.05 mA | 144 | rated from 10 V. Low-noise audio dual; needs at least ±5 V (10 V) and draws about 2 mA per amplifier. |
| 4580 | bipolar | 4–36 V | 15 MHz | 5 V/µs | 3 mA | 103 | Low-noise, high-output-current audio dual from ±2 V; the DIP8 (NJM4580D) is listed as discontinued. | |
| NE5532 | bipolar | 10–30 V | 12 MHz | 5 V/µs | 5 nV | 3 mA | 155 | rated from 10 V. Low noise and strong output drive, but draws about 3 mA per amplifier and has 200 nA bias current. |
| NJM2100 | bipolar | 2–7 V | 12 MHz | 4 V/µs | 1.75 mA | 1 | 7 V max, not for 18 V; much slower. Low-voltage dual op-amp rated to ±3.5 V (7 V total), so it cannot run straight from 9 V. | |
| OPA2134 | JFET | 5–36 V | 8 MHz | 20 V/µs | 8 nV | 4 mA | 108 | JFET input. FET-input audio op-amp without phase inversion; draws about 4 mA per amplifier, so it is hungry on a 9 V battery. |
| NJM4565D | bipolar | 8–36 V | 10 MHz | 4 V/µs | 2.25 mA | 2 | much slower. Drives 20 V peak-to-peak into 400 Ω; the DIP8 (NJM4565D) is listed as discontinued. | |
| OPA1678 | RR out | 4.5–36 V | 16 MHz | 9 V/µs | 4.5 nV | 2 mA | 6 | rail-to-rail output. Surface-mount only (SOIC-8 and smaller), so a DIP socket needs an adapter; standard dual pinout. |
| TLE2072 | 4.5–38 V | 10.6 MHz | 32 V/µs | 17 nV | 2.4 mA | 1 | Fast, low-bias dual drawing about 2.4 mA per amplifier. | |
| M5216 | 4–32 V | 10 MHz | 3 V/µs | 2.25 mA | 4 | much slower. High-current dual (±100 mA load) meant for headphone drivers. |
