INA1650 SoundPlus™ High Common-Mode Rejection, Low Distortion Differential Line Receiver - INA1650

INA1650 (ACTIVE)

INA1650 SoundPlus™ High Common-Mode Rejection, Low Distortion Differential Line Receiver

 

Description

The INA1650 SoundPlus™ audio line receiver achieves an extremely high common-mode rejection ratio (CMRR) of 91 dB while maintaining ultra-low THD+N of –120 dB at 1 kHz for 22-dBu signal levels. The excellent CMRR performance of the INA1650 is achieved through precise matching of on-chip resistors which deliver far superior matching compared to external components and are immune to mismatches introduced by printed circuit board (PCB) layout. Unlike other line receiver products, the INA1650 CMRR is characterized over temperature and tested in production to deliver consistent performance in a wide variety of applications.

The INA1650 operates over a very-wide-supply range of ±2.25 V to ±18 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 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 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.
