16-bit 500 MSPS high-speed DAC with 2Γ/4Γ/8Γ digital interpolation, 32-pin LFCSP package, high dynamic range and low power. Alternative to AD91xx series.
The SXD1651PE is a 16-bit 500 MSPS high-speed DAC designed for portable and medium-bandwidth applications, supporting 2Γ/4Γ/8Γ digital interpolation filters that effectively reduce input data rate requirements and simplify clock and FPGA interface design. The device uses a 32-pin LFCSP small package with high dynamic range and low power, making it a cost-effective China-based DAC for industrial waveform generation, portable instruments, and communication IF transmit chains.
On-chip integrated configurable digital interpolation and anti-sinc filters, paired with a 16-bit DAC core, deliver excellent SFDR and IMD performance at the output. The low-power architecture makes the SXD1651PE well-suited for battery-powered devices, portable test instruments, and multi-channel low-power transmit boards. The 32-pin LFCSP has a small footprint and simple peripherals for quick integration.
The SXD1651PE benchmarks against ADI's AD91xx series (TxDAC+ waveform generation and communication DACs), covering mainstream applications of the series in resolution, sampling rate, interpolation factors, and package. Standard lead time is approximately 6 weeks, suitable for consumer/industrial/communication China-based replacement across multiple scenarios.
