Description
The ADS54J40 is a low-power, wide-bandwidth, 14-bit, 1.0-GSPS, dual-channel, analog-to-digital converter (ADC). Designed for high signal-to-noise ratio (SNR), the device delivers a noise floor of –158 dBFS/Hz for applications aiming for highest
dynamic range over a wide instantaneous bandwidth. The device supports the JESD204B serial interface with data rates up to 10.0 Gbps, supporting two or four lanes per ADC. The buffered analog input provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy. Each ADC channel optionally can be connected to a wideband digital down-converter (DDC) block. The ADS54J40 provides excellent spurious-free dynamic range (SFDR) over a large input frequency range with very low power consumption.
