The AD9142A is a dual, 16-bit, high dynamic range
Digital-to-analog converters(DAC), which provides a sample rate of 1600 MSPS and can generate multiple carriers up to the Nyquist frequency. The AD9142A TxDAC+ features optimized for direct conversion transmission applications, including complex digital modulation, input signal power sensing, and gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators such as Analog Devices' ADL537x F-MOD family and ADRF670x family of modulators. The 3-wire serial port interface allows programming and readback of many internal parameters. The full-scale output current can be programmed from 9 mA to 33 mA. The AD9142A is available in a 72-lead LFCSP package.
Product features
- Wide signal bandwidth (BW) supports emerging wideband and multiband wireless applications.
- Advanced low-spurious and distortion design techniques enable high-quality synthesis of wideband signals from baseband to high IF signals.
- Minimal inherent latency differences simplify hardware and software design in the system. Most applications enable easy multi-chip synchronization.
- The new low-power architecture improves power efficiency (mW/MHz/channel) by 30%.
- Input signal power and FIFO error sensing simplify downstream analog circuit protection design.
- Programmable transmit enable enables a design balance between power consumption and wake-up time.
