AD667JN/+ - 12-Bit DAC, 10V Output | Analog Devices
MPN: AD667JN/+ ✗ जीवन की समाप्तिAD667JN/+ अवलोकन
A digital-to-analog converter is a data-conversion integrated circuit that translates a digital code into a proportional analog voltage or current. The AD667 belongs to the voltage-output DAC hierarchy, which combines a digital interface, voltage reference, resistor network, output amplifier, and current-steering core on one monolithic chip. The double-buffered latch allows a new input word to be loaded while the previous code is being converted, supporting faster system updates than an unbuffered converter.
Key features include 12-bit resolution, a maximum 10 V analog output, and approximately 4 microsecond settling time. The manufacturer also describes monotonicity as guaranteed over temperature and linearity as guaranteed over temperature at 1/2 LSB maximum. A laser-trimmed thin-film resistor network supports accuracy and repeatability, while the integrated buried Zener reference supplies the internal voltage needed by the converter. The AD667JN/+ is identified as a commercial-temperature, through-hole component.
Internally, the AD667 uses 12 precision high-speed bipolar current-steering switches to implement the digital-to-analog conversion. The laser-trimmed resistor network and integrated reference remove the need for external precision reference components. Its microprocessor-compatible double-buffered input architecture supports digital control systems, while the integrated output amplifier provides a voltage output from a single converter package.
Typical applications include closed-loop industrial control, programmable test equipment, digital waveform generation, laboratory instrumentation, data-acquisition systems, and legacy industrial automation platforms. The dual-supply arrangement accommodates bipolar output signals and analog circuits that require both positive and negative rail headroom. The through-hole PDIP package is also suitable for repair and modernization of legacy boards where a surface-mount converter would require layout changes.
When designing around the AD667JN/+, verify the analog output range, supply polarity, settling-time requirement, and logic-interface voltage before assigning signals. Keep analog and digital return currents separated where practical, and use the manufacturer pin-description table to connect the input latch, reference, amplifier, and supply pins. Because the converter is a legacy through-hole device, confirm package pin compatibility during any replacement qualification.
This page organizes the AD667JN/+ electrical characteristics, verified package information, direct replacement candidates, comparison parameters, and practical selection guidance. It emphasizes what an engineer must verify when using this converter in a new design or maintaining an existing analog-control board.

सामान्य अनुप्रयोग
AD667JN/+ के लिए उपयुक्त है 6 अनुप्रयोगs: Industrial Process Control, Programmable Test Equipment, Digital Waveform Generation, Data-Acquisition Systems, Legacy Equipment Repair, Audio and Communication Test Signals.
Industrial Process Control
The AD667JN/+ fits legacy industrial process controllers because it converts a digital command into a bipolar analog control voltage while providing approximately 4 microsecond settling time. Its 12-bit resolution gives 4096 digital codes, and the integrated double-buffered input latch supports controlled updates from a microprocessor or programmable controller. The 28-pin PDIP format also simplifies repairs on legacy control boards. Confirm the required ±12 V or ±15 V supply arrangement, analog output span, and isolation boundaries before connecting it to an actuator or sensor-conditioning loop.
Programmable Test Equipment
The AD667JN/+ is appropriate for laboratory and production test systems that require a calibrated 12-bit voltage command with a maximum 10 V output. Its approximately 4 microsecond settling time allows the test sequence to advance quickly after a code change, while the integrated reference and laser-trimmed resistor network simplify board design. Use the double-buffered input latch for controlled loading, and validate the output accuracy against the 1/2 LSB maximum linearity specification before using it as a precision reference source.
Digital Waveform Generation
The AD667JN/+ can generate stepped and low-frequency waveforms for machinery testing, education equipment, and embedded control prototypes. Its 12-bit DAC core provides 4096 output levels, while the high-speed bipolar current-steering switches and listed 4 microsecond settling time support rapid code updates. The integrated output amplifier simplifies the analog output stage, but waveform quality depends on the selected code sequence, output reconstruction, board layout, and power-supply cleanliness.
Data-Acquisition Systems
The AD667JN/+ serves as a programmable analog output in data-acquisition and instrumentation systems requiring a voltage command from a digital controller. Its 12-bit resolution supports multi-level excitation or calibration signals, and the double-buffered latch allows input data to be staged for subsequent conversion. For closed-loop measurement systems, allow the converter to settle before capturing the response and account for offset and gain errors during calibration.
Legacy Equipment Repair
The AD667JN/+ is particularly useful for maintaining industrial automation, analyzers, and laboratory instruments built around the original 28-pin PDIP device. A pin-compatible approach preserves component placement and avoids a redesign to a surface-mount DAC. The AD667JNZ is the leading replacement candidate because cross-reference information identifies it as a direct substitute. Before installation, compare the ordering suffix, package construction, temperature grade, and board documentation.
Audio and Communication Test Signals
The AD667JN/+ can produce stepped excitation signals for audio amplifier testing, communications equipment alignment, and bench calibration systems. The converter's 10 V maximum output and dual-supply operation can support larger signal ranges than a single-supply converter, while its 12-bit resolution establishes the code granularity. The specified settling time is suitable for relatively slow test sequences rather than high-bandwidth waveform generation. Use appropriate output attenuation or filtering when the target signal requires a lower amplitude or smoother transition.

डिज़ाइन नोट्स
Use clean dual positive and negative supplies at ±12 V or ±15 V as identified for the AD667 family. Verify polarity and sequencing against the manufacturer pin description before energizing the board. Keep high-current return paths away from the reference and converter ground connections, because supply disturbance can appear directly in the analog output and disturb the 12-bit conversion result.
Route the digital input bus away from the analog output and reference-return paths. Place any local bypass capacitors directly at the relevant supply pins, and maintain a low-impedance ground connection between the required ground pins. For a through-hole retrofit, reproduce the original manufacturer's component placement where possible because lead lengths and loop area affect susceptibility to switching noise.
Do not treat every 28-pin AD667 ordering suffix as automatically interchangeable in every assembly. Compare the AD667JN/+ with the selected alternative for package construction, temperature grade, and lifecycle requirements. Also allow the listed 4 microsecond settling time before sampling the output when accuracy matters; the double-buffered latch stages the code but does not eliminate the analog settling interval.
