Stereo high performance 16-bit DAC
Product specification
TDA1541A
True 16-bit performance is achieved by each channel using three 2-bit active dividers, operating on the dynamic element
matching principle, in combination with a 10-bit passive current divider, based on emitter scaling. All digital inputs are
TTL compatible.
