Features 135MSPS Wide dynamic range: SFDR at 1MHz fout: 85dBc, SFDR at 5MHz fout: 79dBc, SFDR at 20MHz fout: 70dBc Differential Current Outputs Low power dissipation: 185mW Very small package: 48-pin TSSOP TTL/CMOS (+3.3V or +5V) inputs Description The DAC14135 is a monolithic 14-bit, 135MSPS digital-to-analog converter. The device has been optimized for use in cellular base stations and other applications where high resolution, high sampling rate, wide dynamic range, and compact size are required. The DAC14135 has many integrated features including a proprietary segmented DAC core, differential current outputs, a band-gap voltage reference, and TTL/CMOS compatible inputs. The converter features an 85dBc spurious free dynamic range (SFDR) at low frequencies and a 70dBc SFDR with 20MHz output signals. The 48-pin TSSOP package provides an extremely small footprint for applications where space is a critical consideration. The DAC14135 operates from a single +5V power supply. The digital power supply can also operate from +3.3V for lower power consumption and compatibility with +3.3V data inputs. The DAC14135 is fabricated in a 0.5µm CMOS process and is specified over the industrial temperature range of -40°C to +85°C. National Semiconductor thoroughly tests each part to verify full compliance with the guaranteed specifications. Applications Cellular Basestations: GSM, WCDMA, DAMPS, etc. Direct digital synthesis (DDS) Multi-carrier Basestations Multi-standard Basestations ADSL modems HFC modems
