The INA1650-Q1 SoundPlus™ audio line receiver achieves an extremely high common-mode rejection ratio (CMRR) of 91 dB while maintaining ultra-low THD+N of –119 dB at 1 kHz for 20-dBu signal levels. Unlike other line receiver products, the INA1650-Q1 CMRR is characterized over temperature and tested in production to deliver consistent performance in a wide variety of applications.
The INA1650-Q1 operates over a very-wide-supply range of ±2.25 V to ±12 V, on 10.5 mA of supply current. In addition to the two line-receiver channels, a buffered midsupply reference output is included to allow the INA1650-Q1 to be configured for dual- or single-supply applications. The mid-supply output can be used as a bias voltage for other analog circuitry in the signal chain.
The INA1650-Q1 features a unique internal layout for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded. This device is specified from –40°C to +125°C.
