The AD9238BSTZ-65 is a dual 12-bit, 65 MSPS analog-to-digital converter (ADC) manufactured by Analog Devices, designed as a high-speed simultaneous-sampling data acquisition solution for multi-channel systems. This device integrates a pair of matched ADCs with a shared reference and clock path, supporting multiplexed or independent analog inputs. Key characteristics of the family include a differential pipeline architecture with user-selectable input span, internal voltage reference, and duty cycle stabilizer circuitry that maintains rated performance over a wide range of clock duty cycles. The LQFP package provides a compact surface-mount footprint while enabling efficient heat dissipation for continuous high-speed operation over the industrial temperature range.
Typical applications include digital receivers where the dual channels serve I/Q demodulation paths in communications infrastructure, medical imaging front-ends such as ultrasound beamforming, and portable test equipment requiring synchronous dual-channel digitization at moderate resolution. In defense and aerospace systems, the simultaneous sampling capability supports phased-array processing and radar IF sampling. From a procurement standpoint, this part does not carry a MIL-STD-883 or similar suffix, so it represents an industrial-grade component rather than a military-qualified device. It is manufactured by Analog Devices, which typically supports extended product lifecycles for high-reliability markets, but design teams should verify the latest obsolescence roadmap and consider lifetime buy options if the system has long qualification cycles. The Z suffix indicates RoHS compliance, making it suitable for designs requiring lead-free processing.
