AD7245JN

Overview

The AD7245JN is a 12-bit voltage-output digital-to-analog converter (DAC) from the DACPORT family, manufactured by Analog Devices. It integrates an output amplifier and a buried Zener voltage reference on a monolithic CMOS chip. The device operates with supply voltages ranging from +10.8 V to +16.5 V for both analog and digital sections. Key performance specifications include a settling time of 5 µs to within ±1/2 LSB, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. It features a parallel interface and is housed in a 24-lead PDIP package.

Feature Summary

• 12-bit resolution with integrated output amplifier and internal 5 V reference
• Parallel data interface with double-buffered logic and CLR input
• Settling time of 5 µs max with ±1 LSB DNL and INL linearity
• Single or dual supply operation with power dissipation of 450 mW

Applications

• Microprocessor-controlled instrumentation systems
• Programmable gain amplifiers and signal conditioning
• Industrial process control loops requiring precise voltage generation

Procurement Notes

Verify the specific suffix 'JN' corresponds to the 24-lead PDIP package and commercial temperature range when sourcing. Confirm RoHS compliance status as manufacturing processes may vary. Check for obsolescence notices or lifecycle status updates directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select the AD7245JN for applications requiring a single-channel 12-bit DAC with high speed and low power consumption. Ensure the system supports parallel loading structures and provides appropriate supply rails between 10.8 V and 16.5 V. Consider the AD7248A if an 8-bit wide bus interface is preferred over the 12-bit parallel structure.
