SBOS772C August 2017 – May 2019 INA1650-Q1 , INA1651-Q1
PRODUCTION DATA.
The INA1650-Q1 dual-channel and INA1651-Q1 single-channel (INA165x-Q1) SoundPlus™ audio line receivers achieve an extremely high common-mode rejection ratio (CMRR) of 91 dB while maintaining an ultra-low THD+N of –119 dB at 1 kHz for 20-dBu signal levels. Unlike other line receiver products, the INA165x-Q1 CMRR is characterized over temperature and tested in production to deliver consistent performance in a wide variety of applications.
The INA165x-Q1 devices operate over a very-wide-supply range of ±2.25 V to ±12 V. In addition to the line-receiver channels, a buffered midsupply reference output is included to allow the INA165x-Q1 to be configured for dual-supply or single-supply applications. The midsupply 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.
