Rochester Electronics Data Acquisition - Data Acquisition - Digital to Analog Converters (DAC) - AD7237ATQ AD7237ATQ

The AD7237ATQ is a dual 12-bit digital-to-analog converter (DAC) designed for applications requiring precise voltage output. It operates within a supply voltage range of 12 V to 15 V and features a low power consumption of approximately 165 mW in single supply mode. The device includes on-chip voltage reference, output amplifiers, and reference buffer amplifiers, eliminating the need for external trims to achieve specified performance. This DAC supports both single and dual supply operations, providing output voltage ranges of 0 V to +5 V and 0 V to +10 V for single supply, and adding a -5 V range for dual supplies. The AD7237ATQ is compatible with microprocessors, featuring a double buffered interface structure that allows for efficient data loading in two write operations. It also includes an asynchronous LDAC signal for updating DAC latches and analog outputs. The device is fabricated using Linear Compatible CMOS (LC¬=MOS) technology, ensuring a compact design and enhanced reliability. It is available in a 24-pin dual-in-line package (DIP) and is rated for an extended temperature range of -55 ¬8C to +125 ¬8C, making it suitable for industrial applications. The specifications indicate a maximum relative accuracy of -1/2 LSB and a settling time of 5 ms for full-scale changes, which are critical for high-performance applications.
