Overview
The ADS5409IZAYR is a high-performance, dual-channel 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed to operate at a maximum clock rate of 900 Msps, making it suitable for high-speed data acquisition and signal processing applications. The ADS5409 features low-noise performance and outstanding spurious-free dynamic range (SFDR) over a wide input-frequency range, ensuring high linearity and accuracy in various demanding environments.
The ADC includes an analog input buffer with high impedance, which isolates the internal switching of the on-chip track-and-hold from disturbing the signal source. It also supports optional 2x decimation with low-pass or high-pass filters, enhancing its versatility in different application scenarios.
