AD5445YCPZ

Digital To Analog Converters Overview

The AD5445YCPZ is a 12-bit, high-bandwidth multiplying digital-to-analog converter (DAC) from Analog Devices. It features a parallel interface with a 17 ns write cycle and an update rate of 20.4 MSPS. The device operates on a single 2.5 V to 5.5 V supply and supports ±10 V reference inputs. Key performance metrics include an INL of ±1 LSB and a 10 MHz multiplying bandwidth. It utilizes a CMOS submicron process for excellent four-quadrant multiplication characteristics. The component is housed in a 20-lead LFCSP package and functions within an extended temperature range of –40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific Y suffix indicates the extended industrial temperature range (-40°C to +125°C). Confirm the CPZ suffix corresponds to the 20-lead LFCSP package variant. Ensure compatibility with external reference voltages up to ±10 V. Check for moisture sensitivity requirements during storage and handling.

Digital To Analog Converters Selection Notes

Select this model when 12-bit accuracy and high-speed parallel data transfer are required. The integrated feedback resistor simplifies voltage output configurations when used with external amplifiers. Consider the 20.4 MSPS update rate for dynamic signal generation needs. Verify that the system logic levels align with the specified VIH and VIL thresholds.

Digital To Analog Converters Part Context

The AD5445 serves as a direct upgrade to the AD7545, offering improved multiplying bandwidth performance while maintaining pin compatibility in chip-scale packages. It belongs to a family including the 8-bit AD5424 and 10-bit AD5433, sharing similar interface and power specifications but differing in resolution and linearity accuracy.

Digital To Analog Converters Replacement Considerations

The AD7545 is a pin-compatible predecessor. Ensure the application does not require transparent mode operation, as the AD5445 uses a latched interface.
