DAC7545JP

Digital To Analog Converters Overview

The DAC7545JP is a CMOS, 12-bit multiplying digital-to-analog converter featuring input data latches and an SO-20 package. It operates on a single +5V to +15V supply with TTL/CMOS logic compatibility. The device provides four-quadrant multiplication capability and ensures monotonicity over the commercial temperature range of -40°C to +85°C. Static accuracy for the JP grade is specified at ±2 LSB relative accuracy and ±20 LSB gain error (with internal RFB) at VDD = +5V. Key dynamic parameters include a current settling time of 2 µs to 1/2 LSB and a propagation delay of 300 ns.

Digital To Analog Converters Feature Summary

• Four-quadrant multiplication capability for analog signal processing
• Monotonicity ensured over the full commercial temperature range
• Low output leakage current of 10nA maximum
• Direct replacement compatibility with AD7545 and PM-7545

Digital To Analog Converters Applications

• Unipolar and bipolar operation using external operational amplifiers
• Digitally controlled gain blocks utilizing the internal R-2R ladder feedback
• Microprocessor interfaces via 8-bit or 16-bit data buses

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific JP grade accuracy specifications match design requirements. Check for RoHS compliance status as indicated in official documentation. Ensure handling precautions are followed due to ESD sensitivity. Review the latest datasheet for any updates regarding availability or pinout configurations before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select the DAC7545JP when 12-bit resolution and four-quadrant multiplying functionality are required. This grade offers ±2 LSB static accuracy suitable for moderate precision applications. Consider the SO-20 package constraints and single-supply voltage range of 5V to 15V. Evaluate the need for external gain adjustment circuits if tighter linearity than the specified ±20 LSB gain error is necessary for the target application environment.

Digital To Analog Converters Part Context

The DAC7545 belongs to Texas Instruments' family of low-cost CMOS multiplying DACs. It utilizes laser-trimmed thin-film resistors and CMOS voltage switches to achieve true 12-bit linearity. The device is designed for microprocessor-compatible systems and battery-powered applications due to its low power dissipation characteristics. It serves as a functional equivalent to older industry-standard parts like the AD7545.

Digital To Analog Converters Replacement Considerations

The DAC7545JP is listed as Not Recommended for New Designs (NRND). The DAC7545JU is an active alternative within the same series offering similar SO-20 packaging but potentially different accuracy grades. Verify electrical parameter compatibility and pinout equivalence before substituting.
