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.

The INA165x-Q1 family combines high-performance audio operational amplifier cores with high-precision resistor networks to provide exceptional audio performance and rejection of noise that may be externally coupled into the audio signal path. The two line-receiver channels of the INA1650-Q1, and the single line receiver channel of the INA1651-Q1, use an instrumentation amplifier topology with a fixed unity gain to provide high input impedance and a high common-mode rejection ratio (CMRR). Unlike other line receiver products that use a simple four-resistor difference amplifier topology, the INA165x-Q1 topology provides excellent CMRR even with mismatched source impedances.
