OPA1612 1.1nV/√Hz 噪声、低功耗精密运算放大器
The OPA1611 (single) and OPA1612 (dual) bipolar-input operational amplifiers achieve very low 1.1nV/√Hz noise density with an ultralow distortion of 0.000015% at 1kHz. The OPA1611 and OPA1612 offer rail-to-rail output swing to within 600mV with a 2k
load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30mA.
These devices operate over a very wide supply range of ±2.25V to ±18V, on only 3.6mA of supply current per channel. The OPA1611 and OPA1612 op amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions.
The dual version features completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded
