AD7537JN

AD7537JN Description

The AD7537JN from Analog Devices Inc. is a high-precision 12-bit dual-channel digital-to-analog converter (DAC) designed for demanding industrial and instrumentation applications. Housed in a 24-pin DIP package, this obsolete but robust DAC offers parallel data interface and requires dual power supplies (10.8V to 16.5V for both analog and digital domains). With a settling time of 1.5µs and ±1 LSB max INL/DNL, it ensures accurate and fast signal conversion. The device supports external voltage reference, enabling flexible output scaling. Its through-hole mounting and MSL 3 (168 hours) rating make it suitable for prototyping and legacy systems.

AD7537JN Features

• Dual 12-bit DACs: Two independent converters in one package, reducing board space and cost.
• High Accuracy: ±1 LSB max integral and differential non-linearity for precise output.
• Fast Settling Time: 1.5µs ensures rapid response in dynamic applications.
• Wide Supply Range: 10.8V to 16.5V for both analog and digital sections, enhancing compatibility.
