AD9238BCPZ-20

AD9238 is a dual, 3V, 12-bit, analogue-to-digital converter (ADC). It features dual high performance sample-and-hold amplifiers (SHAs) and an integrated voltage reference. The wide bandwidth, differential SHA allows for a variety of user-selectable input ranges and offsets, including single-ended applications. It is suitable for various applications, including multiplexed systems that switch fullscale voltage levels in successive channels and for sampling inputs at frequencies well beyond the Nyquist rate. Dual single-ended clock inputs are used to control all internal conversion cycles. A duty cycle stabilizer is available and can compensate for wide variations in the clock duty cycle, allowing the converter to maintain excellent performance. It is widely used in application such as ultrasound equipment, direct conversion or IF sampling receivers, WB-CDMA, CDMA2000, WiMAX, battery-powered instruments, hand-held scopemeters, low cost, digital oscilloscopes etc.
