OPA1612AIDR

OPA1612AIDR is the tape-and-reel SOIC-8 ordering code for the Texas Instruments OPA1612 dual audio operational amplifier, a current orderable code. Its verified figures are the audio specification set: input noise of 1.1 nV/√Hz at 1 kHz, THD+N of 0.000015 % at 1 kHz, a slew rate of 27 V/µs, gain-bandwidth of 40 MHz and quiescent current of 3.6 mA per channel, on supplies of ±2.25 V to ±18 V. The selection point is the noise-and-distortion floor: this is the op amp for the input stage of a DAC output, a phono or line preamplifier, or a measurement front end where the amplifier must add nothing audible or measurable of its own. Selection advice: the performance is specified on dual supplies; a single 5 V design cannot use this code’s swing or its distortion figures, so confirm the rails exist before substituting it for a general-purpose dual.
