AD9253 4-channel, 14-bit, 80/105/125 MSPS, serial LVDS, 1.8 V ADC
The AD9253 is a 4-channel, 14-bit, 80 MSPS/105 MSPS/125 MSPS analog-to-digital converter (ADC) with built-in on-chip sample-hold circuitry designed for low cost, low power consumption, small size, and ease of use. With a slew rate of up to 125 MSPS, it offers outstanding dynamic performance and low power consumption, making it ideal for applications in small package sizes.
The ADC requires a single 1.8 V supply and an LVPECL/CMOS/LVDS compatible sample rate clock signal to maximize its performance. For most applications, there is no need for an external reference or driver piece.
To obtain the appropriate LVDS serial data rate, the ADC automatically multiplies the sample rate clock. It provides a data clock output (DCO) to capture data at the output and a frame clock output (FCO) to send a new output byte signal. It also supports each channel to enter the power-saving state separately; Typical power consumption is less than 2 mW when all channels are disabled. The ADC has a variety of built-in features that allow for optimal device flexibility and minimal system cost, such as programmable clock and data alignment, generation of programmable digital test codes, and more. Available digital test codes include built-in fixed and pseudo-random codes, as well as user-defined test codes entered via the Serial Port Interface (SPI).
The AD9253 is available in a 48-pin LFCSP package and is RoHS compliant. Rated for -40°C to +85°C industrial temperature range. This product is protected by a U.S. patent.
