OPA1612AIDRGR

The OPA1611 (single-channel) and OPA1612 (dual-channel) bipolar-input op-amps achieve ultra-low noise density (1.1nV/√Hz) at 1kHz and ultra-low distortion (0.000015%). They provide rail-to-rail output swing within 600mV of the supply rails under a 2-kΩ load, helping to maximize dynamic range. These devices also feature ±30mA high output drive capability. These devices support a wide supply voltage range of ±2.25V to ±18V with only 3.6mA quiescent current per channel. The OPA1611 and OPA1612 op-amps are unity-gain stable and maintain excellent dynamic performance across a wide range of load conditions. The dual-channel version features fully independent circuitry, ensuring minimum inter-channel crosstalk and zero interaction even under overdrive or overload conditions. The OPA1611 is available in an SOIC-8 package, and the OPA1612 in a SON-8 package. These devices are rated for an operating temperature range of -40°C to +85°C.
