The OPA1622 offers extremely- high ac PSRR and CMRR specifications that • Wide Gain Bandwidth Product: eliminate noise from power supplies, making the 32 MHz (G = +1000) OPA1622 ideal for use in portable-audio applications. • High Slew Rate: 10 V/ μs This device also has a high output-drive capability of • High Capacitive-Load Drive Capability: > 600 pF +145 mA / –130 mA. • High Open-Loop Gain: 136 dB (600- Ω Load) The OPA1622 operates over a very wide supply • Low Quiescent Current: 2.6 mA per Channel range of ±2 V to ±18 V, on only 2.6 mA of supply current per channel. The OPA1622 op amp is unity- • Low-Power Shutdown Mode With Reduced Pop gain stable and provides excellent dynamic behavior and Click Noise: 5 μA per Channel over a wide range of load conditions. The OPA1622 • Short-Circuit Protection includes a shutdown mode, allowing the amplifiers to • Wide Supply Range: ±2 V to ±18 V be switched from normal operation to a standby current that is typically less than 5 µA. This shutdown • Available in small VSON-10 µPackage feature is specifically designed to eliminate click and pop noise when transitioning into or out of shutdown 2 Applications mode. • High-Fidelity (HiFi) Headphone Drivers The OPA1622 features a unique internal layout for • Professional Audio Equipment lowest crosstalk, and freedom from interactions • Analog and Digital Mixing Consoles between channels, even when overdriven or overloaded. This device is specified from –40°C to • Audio Test and Measurement +125°C. • High-End Blu-ray™ Players • High-End Audio and Video (A/V) Receivers Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) OPA1622 VSON (10) 3.00 mm × 3.00 mm (1) For all available packages, see the package option addendum at the end of the datasheet. OPA1622 in a High-Fidelity Headphone Driver FFT: 1 kHz, 32- Ω Load, 50 mW Application 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.
