LTC7545AKN#PBF

Digital To Analog Converters Overview

The LTC7545AKN#PBF is a 12-bit multiplying digital-to-analog converter (DAC) featuring a microprocessor-compatible parallel input. It serves as a pin-compatible replacement for the AD7545A and AD7545, offering improved accuracy and stability over temperature and supply variations. The device operates on a single 5V or 15V supply with low power consumption. Key electrical specifications include an integral nonlinearity (INL) of ±0.5 LSB and a gain error of ±1 LSB maximum at 25°C. The output settling time is typically 1µs, and it supports both 2-quadrant and 4-quadrant multiplication applications.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'KN' corresponds to the commercial grade (0°C to 70°C) in the 20-lead PDIP package. Confirm RoHS compliance status via the manufacturer's official documentation before procurement. Ensure the design accounts for the specified absolute maximum ratings, particularly regarding VDD to AGND voltage limits.

Digital To Analog Converters Selection Notes

Select the LTC7545AKN#PBF when a 12-bit resolution with parallel interface is required for commercial temperature environments. This part is suitable for designs needing direct replacement for legacy AD7545A components. Consider the ±0.5 LSB INL specification for precision applications. Verify that the 20-lead PDIP package fits the board layout constraints compared to SOIC or SSOP alternatives.

Digital To Analog Converters Part Context

The LTC7545A series includes variants such as the AKSW (SOIC), ALN (PDIP), and ABG (SSOP). The 'K' suffix denotes the commercial temperature grade (0°C to 70°C), while 'L' and 'C' denote industrial grades (-40°C to 85°C). The 'N' suffix indicates the 20-lead PDIP package. All variants share the same core functionality and pinout.

Digital To Analog Converters Replacement Considerations

The LTC7545AKN#PBF is explicitly documented as a superior pin-compatible replacement for the AD7545A and AD7545. No other substitute part numbers are listed in the provided datasheet.
