Overview
The AD7262BCPZ-RL7, produced by Analog Devices Inc., is a dual, 12-bit, high-speed, low-power successive approximation analog-to-digital converter (ADC). This component operates from a single 5 V power supply and is designed for applications requiring simultaneous sampling and conversion of two channels. The AD7262 features throughput rates of up to 1 MSPS per on-chip ADC, while the AD7262-5 variant offers throughput rates of up to 500 kSPS. The device includes true differential analog inputs with programmable gain amplifiers (PGA) and supports a wide range of operating temperatures from -40°C to +105°C.
