Texas Instruments OPA1612 Dual Channel, Bipolar Input Audio OP Amp
Texas Instruments launched the OPA1612 dual-channel, bipolar-input audio operational amplifier. The OPA1612 delivers 60% less noise and 50% lower distortion (compared to competitive devices). The amplifier supports multiple channels without significant power consumption. It is ideal for professional audio and broadcast studio equipment, microphone pre-amplifiers, analog and digital mixing consoles, high-end A/V receivers, and audio test and measurement equipment. The OPA1612 is available now in an SO-8 package for $2.75 in 1,000-unit quantities.
OPA1612 Features
- Bipolar input achieves very low 1.1-nV square root Hz noise density with an ultra-low distortion of 0.000015 percent at 1 kHz to enable clear, crisp audio
- Rail-to-rail output swing to within 600 mV with a 2 Ohm load increases headroom and maximizes dynamic range
- Widest supply operation range of +/-2.25 V to +/-18 V from only 3.6 mA of supply current per channel provides excellent dynamic behavior over a wide range of load conditions
- Independent circuitry delivers lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded
- Seamless connectivity to TI audio converters (PCM17xx and PCM16xx) and microphone preamplifiers (PGA2500 and PGA2505) reduces time-to-market
