3 Description
The INA1650-Q1 dual-channel and INA1651-Q1 single-channel (INA165x-Q1) Sound Plus™ audio line receivers achieve an extremely high mon-mode rejection ratio (CMRR) of 91 d B while maintaining an ultra-low THD+N of
- 119 d B at 1 k Hz for 20-d Bu signal levels. Unlike other line receiver products, the INA165x-Q1 CMRR is characterized over temperature and tested in production to deliver consistent...
