OPA1612AID vs OPA1612AIDR vs OPA1632D Comparison

The OPA1612AID is a SoundPlus high performance, dual bipolar input audio operational amplifier in 8 pin SOIC package. This device achieves very low 1.1nV/√Hz noise density with an ultralow distortion of 0.000015% at 1KHz. The OPA1612 offers rail to rail output swing to within 600mV with 2Kohm load which increases headroom and maximizes dynamic range. This op amp is unity gain stable and provides excellent dynamic behaviour over a wide range of load conditions. It has completely independent circuitry for lowest crosstalk and freedom from interactions between channels even when overdriven or overloaded.

The OPA1632D is a fully differential I/O Audio Amplifier designed for driving high-performance audio analogue-to-digital converters. It provides the highest audio quality, with very low noise and output drive characteristics optimized for this application. The OPA1632"s excellent gain bandwidth of 180MHz and very fast slew rate of 50V/µs produce exceptionally low distortion. Very low input noise of 1.3nV/√Hz further ensures maximum signal-to-noise ratio and dynamic range. The flexibility of the fully differential architecture allows for easy implementation of a single-ended to fully-differential output conversion. Differential output reduces even-order harmonics and minimizes common-mode noise interference. The amplifier provides excellent performance when used to drive high-performance audio ADCs. A shutdown feature also enhances the flexibility of this amplifier.
