AD7839 is an eight-channel 13-bit parallel input voltage output DAC with a reference voltage range of -5 V, a maximum output voltage range of -10 V, a clear function to user-defined voltage, and a 44-lead MQFP package
The AD7839 from Analog Devices integrates eight 13‑bit DACs in a single 44‑lead MQFP package. Each channel provides a voltage‑output with a full‑scale range of up to ±10 V, offset adjustment per DAC pair, and a clear function for user‑defined voltages. The device accepts parallel 13‑bit data and can update all outputs simultaneously via the LDAC input.
Designed for automated test equipment and general‑purpose instrumentation, the AD7839 offers high accuracy, low differential nonlinearity, and configurable unipolar or bipolar operation. Typical performance includes a 30 µs settling time, 0.7 V/µs slew rate, and the ability to drive 5 kΩ loads with 50 pF capacitance.
