The OPA1611 and OPA1612 offer rail-to-rail output swing to within 600 m V with a 2-kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30 m A. These devices operate over a very wide supply range of ±2.25 V to ±18 V, on only 3.6 m A 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 pletely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded. Both the OPA1611 and OPA1612 are available in SOIC-8 packages and the OPA1612 is available in SON-8. These devices are specified from - 40°C to +85°C.
