Overview
The AD7264BCPZ-RL7, produced by Analog Devices Inc., is a dual, 14-bit, high-speed, low-power successive approximation analog-to-digital converter (ADC). This device operates from a single 5 V power supply and features throughput rates of up to 1 MSPS per on-chip ADC. It is designed for simultaneous sampling and conversion of two channels, each with a true differential analog input and a programmable gain amplifier (PGA). The AD7264BCPZ-RL7 is available in a 48-lead Lead Frame Chip Scale Package (LFCSP) and is ideal for applications requiring precise measurement and analysis of small amplitude signals from various sensors.
