3 Description
The dual-channel INA1650 and single-channel INA1651 (INA165x) 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
- 120 d B at 1 k Hz for 22-d Bu signal levels. Precision matching of on-chip resistors give the INA165x devices excellent CMRR...
