OPA1652AID

The OPA1652 (dual-channel) and OPA1654 (quad-channel) FET-input operational amplifiers achieve a low noise density of 4.5 nV/√Hz at 1 kHz and ultra-low distortion of 0.00005%. The OPA1652 and OPA1654 operational amplifiers provide rail-to-rail outputs with a swing within 800 mV into a 2 kΩ load, which helps increase headroom and maximize dynamic range. Additionally, these devices feature a high output drive capability of ±30 mA. These devices can operate over a very wide supply voltage range from ±2.25 V to ±18 V, or 4.5 V to 36 V, with a supply current of only 2 mA per channel. The OPA1652 and OPA1654 series operational amplifiers are unity-gain stable and offer excellent dynamic performance over a wide load range. They also use a fully independent circuitry to minimize crosstalk and are immune to inter-channel interaction interference even during overdrive or overload conditions. The OPA1652 and OPA1654 are specified over a temperature range of -40°C to +85°C.
