LHA8831
The LHA8831 is a 12-bit, 2.5 MSPS serial sampling analog-to-digital converter drawing only 5 mA supply current when operated from a single 3 V or 5 V supply. Integrating a low-drift voltage reference (max 20 ppm/℃) and reference buffer, the LHA8831 delivers a low-cost, high-performance, space-saving signal acquisition solution.
The device achieves excellent AC performance of 70 dB SINAD and −85 dB THD at a sampling rate of 2.5 MSPS. Its superior throughput-to-power ratio makes the LHA8831 ideal for compact, low-power, high-speed systems.
The LHA8831 features a high-speed SPI-compatible serial interface supporting 1.8 V, 2.5 V, 3 V and 5 V logic levels. Fast 2.5 MSPS throughput with zero cycle latency suits a wide range of high-speed sensing applications.
