LTC7541AKN#PBF

Digital To Analog Converters Overview

The LTC7541AKN#PBF is a 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an 18-lead PDIP package and operates on a single supply voltage ranging from 5V to 15V. The device utilizes laser-trimmed thin-film resistors to achieve high absolute accuracy, with integral nonlinearity (INL) and differential nonlinearity (DNL) guaranteed at ±0.5 LSB over the commercial temperature range of 0°C to 70°C. It provides current output and supports TTL and CMOS logic inputs. Key performance metrics include a maximum gain error of ±1 LSB at 25°C and a typical settling time of 600 ns for full-scale changes.

Digital To Analog Converters Procurement Notes

Verify that the component matches the specific 'KN' suffix designation for the 18-lead PDIP package and the 'K' grade for the 0°C to 70°C operating temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Digital To Analog Converters Selection Notes

Select this part when a direct upgrade to industry-standard AD7541A components is required without board redesign. Ensure the application requires unbuffered current output and can accommodate external operational amplifiers for voltage conversion. Verify that the parallel digital interface aligns with the system's microcontroller or processor capabilities.

Digital To Analog Converters Part Context

This component belongs to the LTC7541A family of improved industry standard CMOS 12-bit multiplying DACs. The 'KN' suffix indicates the 18-lead Plastic Dual In-Line Package (PDIP), while the 'K' grade specifies the commercial temperature range. It serves as a drop-in replacement for legacy Linear Technology and Analog Devices parts in existing hardware architectures.

Digital To Analog Converters Replacement Considerations

The datasheet identifies the LTC7541A as a superior pin-compatible replacement for the AD7541A and AD7541. Designers upgrading from these legacy parts should verify that the improved stability and reduced sensitivity to output amplifier offset meet their specific circuit requirements.
