描述 Description

DESCRIPTION
The PCM67 and PCM69A dual 18-bit DAC are low cost, dual output 18-bit BiCMOS digital-to-analog converters utilizing a novel architecture to achieve excel lent low level performance.
By combining a conventional thin-film R-2R ladder DAC, a digital offset technique with analog correction and an advanced one-bit DAC using first order noise shaping technique, the PCM67 and PCM69A achieve high resolution, minimal glitch, and low zero-crossing distortion.FEATURES
●18-BIT RESOLUTION DUAL AUDIO DAC
●EXCELLENT THD PERFORMANCE:
?? 0.0025% (–92dB) at F/S, K Grade
?? 1.0% (–40dB) at –60dB, K Grade
●HIGH S/N RATIO: 110dB typ (IHF-A)
●DUAL, CO-PHASE
●SINGLE SUPPLY +5V OPERATION
●LOW POWER: 75mW typical
●CAPABLE OF 16X OVERSAMPLING
●AVAILABLE IN SPACE SAVING 16-PIN DIP OR 20-PIN SOIC
●OPERATING TEMP RANGE: –25°C to +85°C
●EXTREMELY LOW GLITCH ENERGY
