The AD7841 is an eight-channel 14-bit parallel input voltage output DAC chip launched by Analog Devices, which has voltage output, offset adjustment, reference range of ±5V, maximum output voltage range of ±10V-15V, 10% error, clear function, 44-pin MQFP package and other features.
The AD7841 is a monolithic integrated circuit containing eight 14-bit Digital-to-Analog Converters (DACs) in a single package. It features voltage outputs with a full-scale range of ±10 V, driven by reference voltages of ±5 V. The device accepts 14-bit parallel loaded data from an external bus into one of eight input registers, controlled by the WR, CS, and channel address pins (A0–A2).
