Description

The OPA1602 and OPA1604 bipolar-input operational amplifiers achieve very low 2.5nV/√Hz noise density with an ultralow distortion of 0.00003% at 1kHz. The OPA1602 and OPA1604 series of op amps offer rail-to-rail output swing to within 600mV with 2kΩ 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 2.6mA of supply current per channel. The OPA1602 and OPA1604 are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions.

These devices also feature completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.

The OPA1602 and OPA1604 are specified from –40°C to +85°C.
