Dual 16-bit DAC TDA1541
GENERAL DESCRIPTION
The TDA1541 is a monolithic integrated dual 16-bit digital-to-analogue converter (DAC) designed for use in hi-fi digital
audio equipment such as Compact Disc players, digital tape or cassette recorders.
Features
• Selectable two-channel input format: offset binary or two’s complement
• Internal timing and control circuit
• TTL compatible digital inputs
• High maximum input bit-rate and fast settling time.
