AD7840KNZ

The AD7840KNZ from Analog Devices is a high-performance, 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 on a single chip.

This DAC offers versatile interface options, supporting both parallel and serial data input modes. It boasts a fast data setup time of 21 ns for direct parallel interfacing with microprocessors and digital signal processors, and a maximum serial data clock rate of 6 MHz. Key electrical specifications include an 80 dB signal-to-noise ratio, a settling time of 4µs, and an integral nonlinearity (INL) of ±1 LSB.

The AD7840KNZ provides a buffered bipolar output voltage range of ±3V, capable of creating full-power output signals up to 20 kHz. It operates from ±5V supplies and consumes a typical power of 70 mW. The device is fabricated using Linear Compatible CMOS (LC2MOS) technology, combining precision bipolar circuits with low-power CMOS logic.

Packaged in a 24-pin Dual In-line Package (DIP) with through-hole mounting, the AD7840KNZ is suitable for applications requiring accurate voltage output conversion. Its operating temperature range is from 0°C to 70°C.
