| [title] Explore the 1678 OP-Amps | |
| - | [* black] |
| + | [* black] OPA1678 (marked OP1678) by Texas Instruments. Dual channel low noise low distortion operational amplifiers. [https://www.ti.com/lit/ds/symlink/opa1678.pdf?ts=1594918261945|Data sheet]. |
| [* black] The OPA167x amplifiers achieve a low 4.5-nV/√Hz noise density and low distortion of 0.0001% at 1 kHz, which improves audio signal fidelity. They also offer rail-to-rail output swing to within 800 mV with a 2-kΩ load, which increases headroom and maximizes dynamic range. (From the data sheet) | |
| [* black] The OPA1678 and operate over a very wide supply range of ±2.25 V to ±18 V or (4.5 V to 36 V) on only 2 mA of supply current to accommodate the power supply constraints of many types of audio products. These op amps are unitygain stable and have excellent dynamic behavior over a wide range of load conditions. (From the data sheet) | |
| [* black] The OPA167x amplifiers use completely independent internal circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded. (From the data sheet) |
