Audio op-amp with headroom for line-level and headphone drive
The Texas Instruments OPA1622IDRCR is a dual-channel audio operational amplifier from the SoundPlus™ series. It has a 32 MHz gain-bandwidth product and 10 V/µs slew rate.
Supply flexibility and output drive
The supply range spans 4 V to 36 V. Each channel delivers 145 mA of output current.
Temperature range and environment
Rated for -40°C to 125°C, this op-amp suits outdoor audio equipment, automotive infotainment, and industrial sound systems where the ambient temperature exceeds commercial-grade limits. The exposed pad on the 10-VSON package (3x3 mm) should be soldered to a thermal land on the PCB — a via array under the pad to a ground plane keeps the junction temperature within limits when driving continuous audio into low-impedance loads at elevated ambient.
Lifecycle and sourcing
The OPA1622IDRCR is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy schedule is in effect. For BOM planning, this part is sourced through independent distribution and quoted to order against an RFQ.
