Overview
The ADS5404IZAYR is a high-performance, dual-channel, 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed to ease front-end filter design for wide bandwidth receivers, offering high linearity and low-noise performance. The ADC features an analog input buffer with high-impedance input, which isolates the internal switching of the on-chip track-and-hold from disturbing the signal source. It is available in a 196-pin NFBGA (ZAY) package and operates over the full industrial temperature range of –40°C to 85°C.
