AD569JNZ

AD569 is a monolithic voltage output 16bit digital-to-analogue converter (DAC) manufactured in Analog Devices’ BiMOS II process. BiMOS II allows the fabrication of low-power CMOS logic functions on the same chip as high-precision bipolar linear circuitry. The AD569 chip includes two resistor strings, a selector switches decoding logic, buffer amplifiers, and double-buffered input latches. The reference input voltage which determines the output range can be either unipolar or bipolar. The nominal reference range is ±5V and separate reference force and sense connections are provided for high-accuracy applications. Typical applications are robotics, closed-loop positioning, high-resolution ADCs, and microprocessor-based process control.

• Monotonicity to 16bits is insured by the AD569’s voltage segmented architecture
• Output range is ratiometric to an external reference or ac signal
• On-chip output buffer amplifier can supply ±5V into a 1Kohm load
• Low drift, power and noise
• ±0.04% integral nonlinearity (at +25°C)
• ±1LSB differential nonlinearity (at +25°C)
• 0°C to +70°C temperature range
• Power supply sensitivity is ±0.5ppm/% typ (+10.8V ≤ +VS ≤ +13.2V)
• Power supply voltage range from +10.8 to +13.2V (TA=+25°C
• 28-pin plastic DIP package
