MX7845KN

Digital To Analog Converters Overview

The MX7845KN is a complete, dual-channel, 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features an R-2R resistor ladder architecture with integrated output buffers and a parallel bus interface. The device operates on a single supply voltage ranging from 11.4 V to 16.5 V for both analog and digital sections. Key performance specifications include a settling time of 4 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±0.5 LSB. It is housed in a 24-pin narrow PDIP package and supports an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Dual-channel configuration providing two independent 12-bit multiplying DAC outputs within a single integrated circuit.
• Integrated output buffering capability designed to maintain signal integrity without requiring external amplification components.
• Multiplying architecture allowing the reference input voltage to scale the digital code, enabling flexible gain control applications.

Digital To Analog Converters Applications

• Programmable gain amplifier circuits requiring precise analog scaling.
• Waveform generation systems utilizing multiplying DAC functionality.
• Industrial process control instrumentation needing isolated analog outputs.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific suffix variations against current datasheets before procurement. Ensure supply chain sources provide valid traceability documentation for quality assurance purposes.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required to reduce board space compared to single-channel alternatives. Verify that the 12-bit resolution and 4 µs settling time meet system timing requirements. Ensure the parallel interface compatibility matches the host microcontroller or DSP data bus width and protocol.

Digital To Analog Converters Part Context

This part belongs to the Maxim Integrated MX7847/MX7845 family of complete multiplying DACs. These devices are engineered to simplify analog design by integrating precision resistors and buffers. The MX7845KN specifically offers dual channels, whereas related parts may offer single or quad configurations with similar electrical characteristics.

Digital To Analog Converters Replacement Considerations

MX7847KN+ is a verified substitute offering identical electrical specifications but packaged in a 24-pin DIP format instead of narrow DIP. Verify pinout compatibility during replacement to ensure direct interchangeability without PCB redesign.
