Overview
The AD1139J is an 18-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features a parallel data interface and current output type. The device operates with analog supply voltages of 5V and ±15V. Integral nonlinearity (INL) and differential nonlinearity (DNL) are specified at a maximum of ±0.5 LSB. The component is housed in a 32-BBDIP-H package, designed for through-hole mounting. It includes an internal reference and functions as a single-channel precision data converter.
Feature Summary
- 18-bit resolution with ±0.5 LSB INL/DNL accuracy
- Parallel data interface with unbuffered current output
- Internal voltage reference included
- 32-lead BBDIP-H package
Applications
- High-precision industrial control systems
- Test and measurement equipment requiring high resolution
- Medical instrumentation
- Data acquisition systems
Procurement Notes
Verify the specific suffix J against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications relative to other variants like the K. Confirm availability status as some related packages may be discontinued. Ensure the design supports the required ±15V analog supplies and parallel logic levels before procurement.
Selection Notes
Select the AD1139J when 18-bit resolution and low nonlinearity are critical for the application. The parallel interface requires sufficient microprocessor or FPGA pins. Verify that the system can accommodate the 32-pin DIP package and the necessary dual power supplies. Consider thermal dissipation requirements based on the load current.
Part Context
The AD1139 belongs to the AD1139 family of high-accuracy DACs from Analog Devices. This series is designed for applications demanding high linearity and resolution. The part number indicates the specific package and temperature range variant within this product line.
Replacement Considerations
The AD1139K is explicitly noted as no longer available. Check for direct pin-compatible replacements in the same family or equivalent performance DACs from Analog Devices if the AD1139J is also subject to obsolescence.
