OPA1612AQDRQ1

The OPA1612-Q1 is a dual-channel, bipolar-input op amp featuring ultra-low noise density (1.1nV/√Hz at 1kHz) and extremely low distortion (0.000015%). The OPA1612-Q1 provides rail-to-rail output swing within 600mV of either rail under a 2kΩ load, helping to maximize headroom and 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 a quiescent current of only 3.6mA per channel. The OPA1612-Q1 op amp is unity-gain stable and delivers excellent dynamic performance across a wide range of load conditions. The dual-channel version features fully independent circuitry, ensuring minimum crosstalk and zero interaction between channels even under overdrive or overload conditions. The OPA1612-Q1 is available in an SOIC-8 package. The device is rated for an operating temperature range of -40°C to +125°C.
