The OPA1611 and OPA1612 0.000015% at 1 kHz offer rail-to-rail output swing to within 600 mV with a 2-k Ω load, which increases headroom and maximizes • High Slew Rate: 27 V/ μs dynamic range. These devices also have a high • Wide Bandwidth: 40 MHz (G = +1) output drive capability of ±30 mA. • High Open-Loop Gain: 130 dB These devices operate over a very wide supply range • Unity Gain Stable of ±2.25 V to ±18 V, on only 3.6 mA of supply current • Low Quiescent Current: per channel. The OPA1611 and OPA1612 op amps 3.6 mA per Channel are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions. • Rail-to-Rail Output • Wide Supply Range: ±2.25 V to ±18 V The dual version features completely independent circuitry for lowest crosstalk and freedom from • Single and Dual Versions Available interactions between channels, even when overdriven or overloaded. 2 Applications Both the OPA1611 and OPA1612 are available in • Professional Audio Equipment SOIC-8 packages and the OPA1612 is available in • Microphone Preamplifiers SON-8. These devices are specified from –40°C to • Analog and Digital Mixing Consoles +85°C. • Broadcast Studio Equipment Device Information(1) • Audio Test And Measurement PART NUMBER PACKAGE BODY SIZE (NOM) • High-End A/V Receivers OPA1611 SOIC (8) 4.90 mm × 3.91 mm SOIC (8) 4.90 mm × 3.91 mm OPA1612 SON (8) 3.00 mm × 3.00 mm (1) For all available packages, see the orderable addendum at the end of the datasheet. space space THD+N Ratio vs Output Amplitude Functional Block Diagram 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
