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. The device offers both parallel and serial interface options, making it compatible with high-speed DSP processors and microprocessors.
Key electrical specifications include an 80 dB signal-to-noise ratio, a minimum WR pulse width of 45 ns, and a fast data setup time of 21 ns for parallel interfacing. In serial mode, it supports a data clock rate of up to 6 MHz. The analog output provides a bipolar range of ±3V, and full power output signals up to 20 kHz can be generated.
Fabricated using LC2MOS technology, the AD7840JN combines precision bipolar circuits with low-power CMOS logic. It is supplied in a 24-pin Plastic Dual In-line Package (PDIP) suitable for through-hole mounting. The operating temperature range is from 0°C to 70°C.
