Overview of OPA1611AIDR

The OPA1611AIDR is a high-performance, low-distortion operational amplifier (op-amp) manufactured by Texas Instruments. It features ultra-low noise, with a typical input voltage noise density of 1.1 nV/√Hz at 1 kHz, making it suitable for precision audio applications. The OPA1611AIDR has a wide bandwidth of 10 MHz and a slew rate of 20 V/μs, enabling it to faithfully reproduce high-frequency signals with minimal distortion. It operates over a wide supply voltage range of ±2.25 V to ±18 V, offering flexibility in various circuit configurations. The device is available in a small outline package (SOIC) with eight pins, making it suitable for space-constrained designs. With its combination of low noise, wide bandwidth, and high slew rate, the OPA1611AIDR is ideal for high-fidelity audio systems, professional audio equipment, and instrumentation applications where precision and performance are critical
