Overview
The AD7247JNZ is a dual 12-bit digital-to-analog converter (DAC) from the DACPORT series by Analog Devices. It features parallel word input loading and provides buffered voltage outputs. The device operates with analog and digital supply voltages of ±15 V, within a range of 10.8 V to 16.5 V. Key electrical specifications include a settling time of 8 µs, differential nonlinearity (DNL) of ±0.9 LSB, and integral nonlinearity (INL) of ±1 LSB. It supports an external or internal reference type and dissipates up to 300 mW. The component is housed in a 24-pin PDIP package and functions within a temperature range of -55°C to +85°C.
Feature Summary
- Dual-channel 12-bit resolution with R-2R architecture
- Parallel interface with word input loading
- Buffered voltage output capability
- Supports both external and internal reference configurations
Applications
- Industrial process control systems requiring precise analog signal generation
- Data acquisition systems utilizing high-resolution digital-to-analog conversion
- Test and measurement equipment needing stable voltage references
Procurement Notes
Verify the specific suffix JNZ corresponds to the PDIP-24 through-hole package and industrial temperature grade (-55°C to +85°C). Confirm RoHS compliance status for the specific manufacturing lot. Ensure the ordering quantity matches the tube packaging format typically associated with this part number variant.
Selection Notes
Select the AD7247JNZ when a dual-channel solution is required instead of single-channel alternatives like the AD7248. Consider the 8 µs settling time and ±1 LSB INL for accuracy requirements. Compare against surface-mount variants such as the AD7247AARZ if PCB space constraints dictate a change in package type from PDIP to SOIC.
Part Context
The AD7247 belongs to the DACPORT family, which integrates precision DACs with on-chip amplifiers. This series is designed for applications demanding high linearity and fast settling times. The JNZ suffix specifically denotes the plastic DIP package version, distinguishing it from ceramic or surface-mount options within the same functional family.
Replacement Considerations
The AD7247AARZ serves as a pin-compatible surface-mount alternative in a 24-SOIC package. For single-channel requirements, the AD7248JNZ offers similar performance in a 20-PDIP footprint.
