Texas Instruments - Operational amplifier claims industry’s lowest noise, distortion and quiescent current

The amplifier supports multiple channels without significant power consumption in applications such as 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.



Key features and benefits of the OPA1612



· Bipolar input achieves very low 1.1-nV√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
