Overview

The AD7545 is a monolithic 12-bit CMOS multiplying digital-to-analog converter (DAC) featuring onboard data latches. It accepts a single 12-bit wide word and directly interfaces with most 12- and 16-bit bus systems via TTL-compatible inputs. The device operates on a single supply voltage ranging from +5 V to +15 V, dissipating less than 0.5 mW at +5 V. Key static performance metrics include a maximum gain error of ±2 LSB for J/A/S grades and a typical gain temperature coefficient of 2 ppm/°C. Dynamic characteristics specify a current settling time of 2 µs max and a propagation delay of 300 ns max.

Feature Summary

12-bit resolution with R-2R ladder architecture
Onboard TTL-compatible data latches for direct bus interfacing
Single +5 V to +15 V supply operation
Low power consumption (<0.5 mW at VDD = +5 V)
Latch-free design eliminating the need for Schottky protection diodes

Applications

Battery-operated equipment requiring low power
Multiplying DAC applications acting as attenuators
Microprocessor interfacing for 8-bit and 16-bit systems
Applications requiring wide temperature stability

Procurement Notes

Verify the specific grade suffix (e.g., N for Plastic DIP, Q for Cerdip, P for PLCC, E for LCCC) to ensure correct package type and operating temperature range. Military versions require adding /883B to the part number. Confirm that the selected grade meets the required gain error and monotonicity specifications for the target application.

Selection Notes

Select based on required accuracy and temperature range. Grades J, K, L offer commercial temperatures (0°C to +70°C), while A, B, C cover industrial (-25°C to +85°C) and S, T, U cover extended (-55°C to +125°C). Higher accuracy grades (L, GL) have lower gain errors but may require specific trim resistor values. Ensure the output op-amp selection matches the bandwidth requirements, such as using AD544L for fast settling or AD517L for low offset.

Part Context

The AD7545 is part of Analog Devices' family of CMOS multiplying DACs. It serves as a foundational component for precision analog signal generation in mixed-signal systems. The device is often paired with external operational amplifiers like the AD544 or AD517 to buffer the unbuffered current output and define voltage ranges.
