OPA1622IDRCT General Description

The OPA1622, dual, bipolar-input, SoundPlus™ audio operational amplifier achieves a very low, 2.8-nV/√Hz noise density with an ultralow THD+N of –119.2 dB at 1 kHz, while driving a 32-Ω load at 100-mW output power. The OPA1622 offers extremely-high ac PSRR and CMRR specifications that eliminate noise from power supplies, making the OPA1622 ideal for use in portable-audio applications. This device also has a high output-drive capability of +145 mA / –130 mA.

The OPA1622 operates over a very wide supply range of ±2 V to ±18 V, on only 2.6 mA of supply current per channel. The OPA1622 op amp is unity-gain stable and provides excellent dynamic behavior over a wide range of load conditions. The OPA1622 includes a shutdown mode, allowing the amplifiers to be switched from normal operation to a standby current that is typically less than 5 µA. This shutdown feature is specifically designed to eliminate click and pop noise when transitioning into or out of shutdown mode.

The OPA1622 features a unique internal layout for lowest crosstalk, and freedom from interactions between channels, even when overdriven or overloaded. This device is specified from –40°C to +125°C.

Quality at height, all according to the description. I order in this store for the first time and was satisfied. Very fast shipment.

C**n 11/29/2022

Everything works fine. Put in a voltmeter instead of a crown.

Z**e 12/24/2020

Everything came in a month. Packed as expected. Even instructions for use are. But in chinese. Well, at least not in the kulechek packed, but in a normal tight package. The density is closer to the plastic.

A**a 08/18/2020

The parcel went with paid delivery of 32 days to krasnoyarsk. I think i'll check it out.
