AD5324ARM

AD5324ARM Description

The AD5324ARM from Analog Devices Inc. is a 12-bit, quad-channel, voltage-output digital-to-analog converter (DAC) designed for precision analog signal generation. Housed in a compact 10-MSOP package, it integrates four DACs with an SPI/DSP-compatible serial interface, making it ideal for space-constrained applications. The device operates with dual power supplies (2.5V–5.5V analog/digital), ensuring compatibility with mixed-voltage systems. Its ±2 LSB INL and ±0.2 LSB DNL errors ensure high linearity, while a fast 10µs settling time enables rapid dynamic response. The external reference input allows flexible output scaling, and its string DAC architecture provides stable performance over temperature variations.
