Description
The OPA1637 is a low-noise, low total harmonic distortion (THD), fully differential, Burr-Brown™ Audio operational amplifier that easily filters and drives fully differential, audio signal chains.
The OPA1637 also converts single-ended sources to differential outputs required by high-fidelity analog-to-digital converters (ADCs). Designed for exceptional low noise and THD, the bipolar super-beta inputs yield a very low noise figure at very-low quiescent current and input bias current. This device is designed for audio circuits where low power consumption is required along with excellent signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR).
The OPA1637 features high-voltage supply capability, allowing for supply voltages up to ±18 V. This capability allows high-voltage differential signal chains to benefit from the improved headroom and dynamic range without adding separate amplifiers for each polarity of the differential signal. Very-low voltage and current noise enables the OPA1637 for use in high-gain configurations with minimal impact to the audio signal noise.
