ADS6245IRGZT

The ADS6245IRGZT is a dual-channel, 14-bit, 125 MSPS analog-to-digital converter (ADC) from Texas Instruments, part of the ADS624X family. It utilizes a pipelined architecture with differential inputs and a serial LVDS data interface, enabling high-speed data conversion with low noise. Key electrical specifications include a typical signal-to-noise ratio (SNR) of 73.7 dB, spurious-free dynamic range (SFDR) of 87 dB, and an effective number of bits (ENOB) of 11.7 bits. The analog input bandwidth is 500 MHz with a 2 Vpp input voltage range. Power consumption is typically 1000 mW from a 3.0V to 3.6V supply.

The device features simultaneous sampling for both channels, internal and external reference options, and programmable coarse and fine gain settings for optimizing SFDR/SNR trade-offs. It supports a variety of clock inputs including sine, LVCMOS, LVPECL, and LVDS. The ADC is housed in a 48-VFQFN Exposed Pad (7x7 mm) package, surface mountable, and operates over the industrial temperature range of -40°C to 85°C. This combination of high resolution, sampling rate, and dynamic performance makes it suitable for demanding applications such as communications infrastructure, medical imaging, and radar systems.
