AD9253BCPZ-105 14-bit 105 MSPS Dual ADC
The AD9253BCPZ-105 from Analog Devices is a high-performance 14-bit, 105 MSPS dual-channel analog-to-digital converter (ADC) designed for demanding signal processing applications requiring exceptional dynamic range and power efficiency. Housed in a compact 32-lead LFCSP package, this IC integrates two high-speed ADC cores, each capable of sampling at up to 105 million samples per second, making it ideal for applications like communications infrastructure, medical imaging, and aerospace instrumentation. It operates from a single 1.8V power supply and features a configurable LVDS or CMOS digital output interface, providing design flexibility while maintaining low power dissipation of typically 100 mW per channel. The device incorporates advanced functions such as a programmable digital test pattern generator and a flexible clock input structure, supporting both high-performance and cost-sensitive designs that require precise signal acquisition from two synchronous sources.
AD9253BCPZ-105 Key Features
This dual-channel ADC delivers outstanding AC performance with a signal-to-noise ratio (SNR) of 75.5 dB and a spurious-free dynamic range (SFDR) of 90 dBc at 70 MHz input frequency, ensuring accurate digitization of high-speed analog signals. The AD9253BCPZ-105 features an integrated input buffer that simplifies interface design with front-end components and provides a constant input impedance, while its programmable gain and offset adjustment capabilities allow for system calibration and optimization. The device supports a 1.8V CMOS or differential LVDS output option, with a programmable output data pattern for easy signal integrity validation. Additional features include a built-in reference circuit, a sample-and-hold amplifier with wide input bandwidth, and a flexible clock divider that supports various system timing requirements. Operating over the industrial temperature range (-40°C to +85°C), it ensures reliable performance in harsh environments.
