Overview
The ADS54J40IRMPT is a low-power, wide-bandwidth, 14-bit, 1.0-GSPS, dual-channel analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed to deliver high signal-to-noise ratio (SNR) and is ideal for applications requiring high dynamic range over a wide instantaneous bandwidth. The ADC features a noise floor of –158 dBFS/Hz and supports the JESD204B serial interface with data rates up to 10.0 Gbps. It is packaged in a 72-pin VQFNP (RMP) package, measuring 10 mm × 10 mm.
