AD7243AN

AD7243AN Description

The AD7243AN from Analog Devices Inc. is a 12-bit voltage-output digital-to-analog converter (DAC) housed in a 16-pin DIP package. Designed for precision analog signal generation, it features a single-channel output with a settling time of 10µs, making it suitable for applications requiring fast and accurate voltage conversion. The device operates with a dual supply voltage range of ±10.8V to 16.5V and supports both external and internal reference options, providing flexibility in system design. As part of the DACPORT® series, it offers robust performance with ±1 LSB (max) INL/DNL for high linearity.
