Overview
The AD5337ARM-REEL7 is a dual 8-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5337/AD5338/AD5339 family, which includes 8-bit, 10-bit, and 12-bit DACs, respectively. The AD5337ARM-REEL7 operates from a single 2.5 V to 5.5 V supply, consuming a low current of 250 μA at 3 V. It is housed in an 8-lead MSOP package and features a 2-wire (I2C-compatible) serial interface with clock rates up to 400 kHz. The device is designed for low power operation and includes on-chip rail-to-rail output buffer amplifiers, making it suitable for various applications requiring precise voltage output control.
