Product specification

Stereo high performance 16-bit DAC

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.
