Overview
The AD667KNZ is a monolithic 12-bit digital-to-analog converter manufactured by Analog Devices Inc. It features a parallel interface and voltage output type, housed in a 28-pin PDIP package for through-hole mounting. The device operates with an analog supply voltage ranging from 11.4 V to 16.5 V and a digital supply of 5 V. Key performance metrics include a settling time of 3 µs, differential nonlinearity of ±0.25 LSB, and integral nonlinearity of ±0.125 LSB. It dissipates 555 mW of power and functions within a temperature range of -40°C to +85°C.
Feature Summary
- 12-bit resolution with 1 channel
- Parallel data interface
- Voltage output type
- Settling time of 3 µs
Applications
- Industrial process control systems
- Precision instrumentation
- Data acquisition systems
Procurement Notes
Verify the specific suffix KNZ corresponds to the 28-PDIP package and commercial/industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status via the manufacturer's current documentation, as regulatory statuses may change. Ensure the ordering quantity matches the standard tube packaging format specified by Analog Devices for this part number.
Selection Notes
Select the AD667KNZ when a 12-bit resolution and parallel interface are required for voltage output applications. Compare the 3 µs settling time against system timing requirements. Verify that the 11.4 V to 16.5 V analog supply range aligns with available power rails. Consider the PDIP-28 package constraints if board space or thermal dissipation (555 mW) is a limiting factor.
Part Context
The AD667KNZ belongs to the AD667 series of high-speed, low-power DACs from Analog Devices. This series is designed for applications requiring moderate resolution and fast settling times. The KNZ suffix specifically denotes the plastic dual in-line package variant, distinguishing it from ceramic or leadless chip carrier options within the same functional family.
Replacement Considerations
Publicly confirmed substitute part numbers for the AD667KNZ were not identified in the provided source material. Cross-referencing with other 12-bit parallel DACs requires careful evaluation of pin compatibility and electrical specifications.
