AD7541AKNZ

Digital To Analog Converters Overview

The AD7541AKNZ is a 12-bit monolithic multiplying digital-to-analog converter (DAC) from Analog Devices. It features an inverted R-2R ladder architecture with current outputs at OUT1 and OUT2. The device operates on a single supply voltage ranging from 5 V to 16 V, consuming a maximum of 2 mA. It offers ±0.5 LSB relative accuracy and ±3 LSB gain error at 25°C. The component supports full four-quadrant multiplication and guarantees monotonicity over the specified temperature range.

Digital To Analog Converters Feature Summary

• 12-bit resolution with ±0.5 LSB endpoint linearity
• Full four-quadrant multiplying capability
• TTL/CMOS compatible digital inputs with low leakage
• Latch-up proof design without external protection diodes

Digital To Analog Converters Applications

• Waveform generators
• Programmable amplifiers and attenuators
• Digitally controlled calibration
• Programmable filters and oscillators

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix 'K' for ±0.5 LSB accuracy when ordering. Confirm the package type is 18-lead PDIP (N-18). Check RoHS compliance status as indicated by the 'Z' suffix in the part number. Ensure the operating environment stays within the commercial temperature range of 0°C to +70°C.

Digital To Analog Converters Selection Notes

Select the AD7541AKNZ for applications requiring high linearity and monotonic operation. The K-grade version provides tighter accuracy specifications compared to the J-grade. Consider the output settling time of 0.6 µs for speed requirements. Ensure the driving circuitry can handle the TTL/CMOS input levels without excessive loading.

Digital To Analog Converters Part Context

This component is an improved version of the obsolete AD7541. It maintains pin compatibility while offering enhanced performance metrics such as reduced gain error and lower charge injection. The laser wafer trimming ensures precise linearity across the operating temperature range.

Digital To Analog Converters Replacement Considerations

The AD7541AKNZ serves as a direct pin-for-pin replacement for the standard AD7541. Verify that the existing circuit does not rely on Schottky diodes previously used for latch-up protection, as they are no longer required.
