AD9237 is a 12-bit, 20 MSPS/40 MSPS/65 MSPS 3 V low power A/D converter from Analog Devices. It has ultralow power, flexible analog input range, optional binary, twos complement or gray code data formats, output enable pin, 2-step power-down, full power-down and sleep mode, etc. It is suitable for ultrasound and medical imaging, battery-powered instruments, handheld scope meters, low cost digital oscilloscopes, low power digital still cameras and copiers, low power communications, etc.
The AD9237 family is a monolithic 12‑bit analog‑to‑digital converter that operates from a single 3 V supply. It features a high‑performance sample‑and‑hold amplifier, a programmable input range (1 Vpp‑4 Vpp), and a clock‑duty‑cycle stabilizer for reliable operation at high sample rates.
Typical applications include ultrasound and medical imaging, battery‑powered instruments, hand‑held scope meters, low‑cost oscilloscopes, and low‑power digital cameras. The device is supplied in a 32‑lead LFCSP package and is rated for an industrial temperature range of –40 °C to +85 °C.
