1.4 Device Information

The ADS9219 is an 18-bit, 20-MSPS per channel, dual-channel, simultaneous-sampling, analog-to-digital converter (ADC). The ADS9219 integrates an ADC driver, precision voltage reference, reference buffer, and common mode voltage output buffer. Combined with low conversion latency, high sampling rates, minimal AC and DC errors, and low temperature drift, the ADS9219 is a high-performance design for applications requiring both precision and speed.

The serial LVDS (SLVDS) digital interface reduces board layout complexities, relaxes FPGA timing closures, simplifies firmware, and supports full throughput at lower clock speeds.
