AD1139K

Overview

The AD1139K is an 18-bit digital-to-analog converter manufactured by Analog Devices Inc. It features a parallel data interface and delivers current outputs in an unbuffered configuration. The device operates on dual power supplies, requiring 5V for the digital section and ±15V for the analog section. Integral nonlinearity (INL) and differential nonlinearity (DNL) are both specified at a maximum of ±0.5 LSB. It is housed in a 32-lead ceramic dual in-line package (CDIP) with dimensions of 0.910 inches (23.12 mm). The component supports an operating temperature range from 0°C to +70°C.

Feature Summary

18-bit resolution with ±0.5 LSB INL/DNL accuracy
Parallel data interface with unbuffered current output
Dual supply operation: 5V digital, ±15V analog

Applications

High-precision industrial process control systems
Test and measurement instrumentation
Medical equipment requiring accurate signal generation

Procurement Notes

The AD1139K is officially listed as no longer available or obsolete by the manufacturer. Verification of current stock status requires checking authorized distributors directly. Sourcing may involve surplus markets or alternative replacement components due to discontinuation.

Selection Notes

Select this component only if 18-bit resolution and parallel interface compatibility are required. Ensure the system design accommodates ±15V analog supplies and unbuffered current outputs. Verify that the 32-CDIP package footprint fits the target PCB layout constraints.

Part Context

The AD1139K belongs to the AD1139 family of high-resolution DACs. It is distinct from ADC models like the MAX1139 or AD7401 series found in general catalogs. The 'K' suffix typically denotes the commercial temperature range and specific packaging variant within the product line.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the discontinued status, engineers should consult Analog Devices for recommended upgrades or verify pin-compatible alternatives through official technical support channels.
