Product Description

The AD7849CRZ is a 14/16-bit serial input multiplying Digital-to-analog Converter (DAC) with serial input. The DAC architecture ensures excellent differential linearity performance and monotonicity is guaranteed to 14-bit for the A grade and to 16-bit for all other grades over the specified temperature ranges. During power-up and power-down sequences, the VOUT pin is clamped to 0V via a low impedance path. To prevent the output of A3 from being shorted to 0V during this time, Transmission Gate G1 is also opened. These conditions are maintained until the power supplies stabilize and a valid word is written to the DAC register. At this time G2 opens and G1 closes. Both transmission gates are also externally controllable via the reset in control input. For instance, if the RSTIN input is driven from a battery supervisor chip, then at power-off or during a brown out, the RSTIN input is driven low to open G1 and close G2. The DAC must be reloaded with RSTIN high, to reenable the output.
