AD7840JN Description

Short technical summary and product information.

The AD7840JN from Analog Devices is a fast, complete 14-bit voltage output Digital-to-Analog Converter (DAC). It integrates a 14-bit DAC, a 3V buried Zener reference, a DAC output amplifier, and high-speed control logic.

 

This DAC offers versatile interface options, supporting both parallel and serial data input. It boasts a signal-to-noise ratio of 80 dB and a fast WR pulse width of 45 ns, making it suitable for interfacing with high-speed DSP processors. The device operates from ±5V supplies and consumes a typical power of 70 mW.

 

The analog output provides a bipolar range of ±3V. The AD7840JN is fabricated using LC2MOS technology, combining bipolar precision with CMOS logic for low power consumption. It is available in a 24-pin DIP package.

 

Key specifications include a 14-bit resolution, 80 dB signal-to-noise ratio, 45 ns minimum WR pulse width, and a typical power consumption of 70 mW. The operating temperature range is 0 to 70 °C.
