MX7847BR+T

Digital To Analog Converters Overview

The MX7847BR+T is a dual, 12-bit multiplying digital-to-analog converter (DAC) from the MX7837/MX7847 series. It features two independent channels with integrated output amplifiers and feedback resistors, capable of developing ±10V across a 2kΩ load. The device utilizes a 12-bit parallel interface with separate chip select inputs for each channel and a common write input. Electrical specifications include a settling time of 4µs to within ±1/2 LSB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±1/2 LSB. It operates on positive and negative supply voltages ranging from 11.4V to 16.5V. The component is housed in a 24-pin Wide SO package and supports an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the MX7847BR+T designation against official Analog Devices documentation to confirm the specific suffix indicates the wide SOIC package and industrial temperature grade. Ensure compatibility with existing board layouts regarding pin assignments and power supply decoupling requirements before procurement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with high accuracy and fast settling times is required. The internal feedback resistor simplifies design compared to external resistor configurations. Consider the MX7837 variant if an 8-bit bus interface is preferred over the 12-bit parallel interface provided by the MX7847.

Digital To Analog Converters Part Context

The MX7847 belongs to the MX7837/MX7847 family of complete, dual, 12-bit multiplying DACs. This series is designed for applications requiring precise analog signal generation and control. The BR suffix specifically denotes the wide SOIC package option within the industrial temperature range (-40°C to +85°C), distinguishing it from DIP or ceramic variants.

Digital To Analog Converters Replacement Considerations

MX7847AR+ serves as a direct package alternative in the same temperature range. MX7847KN+ offers a DIP package option for through-hole applications. Verify pin compatibility and thermal characteristics when substituting.
