Overview
The AD569KP is a monolithic 16-bit digital-to-analog converter manufactured using Analog Devices’ BiMOS II process. It features a voltage-segmented architecture that guarantees 16-bit monotonicity over temperature and time. The device includes two resistor strings, selector switches, decoding logic, buffer amplifiers, and double-buffered input latches. It operates with ±10.8 V to ±13.2 V power supplies and accepts an external reference range of ±5 V. The output settles to within ±0.001% for a full-scale step in 3 μs typical. The AD569KP is specified for commercial operation from 0 °C to +70 °C and is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package.
Feature Summary
- Guaranteed 16-bit monotonicity via voltage-segmented architecture
- Typical integral nonlinearity of ±0.024% and differential nonlinearity of ±1/2 LSB
- 3 μs typical settling time to ±0.001% for a full-scale step
- Double-buffered input latches support 8- and 16-bit bus compatibility
Applications
- Robotics
- Closed-loop positioning systems
- High-resolution analog-to-digital converters
- Microprocessor-based process control
Procurement Notes
Verify the package designation P-28A corresponds to the required Plastic Leaded Chip Carrier footprint during procurement. Confirm the operating temperature range specification of 0 °C to +70 °C aligns with the system environment requirements. Ensure ESD precautions are observed as the device is sensitive to electrostatic discharge.
Selection Notes
Select the AD569KP when a plastic PLCC package is preferred over ceramic DIP options. This grade offers tighter linearity specifications (±0.024% INL) compared to the JN/JP variants. Ensure the design accommodates the required ±12 V supply rails and external reference voltages for optimal performance.
Part Context
The AD569KP belongs to the AD569 family of 16-bit DACs. It shares the same core functionality and electrical characteristics as the AD569KN but differs in packaging. While the KN variant uses a 28-pin Plastic DIP, the KP variant utilizes a 28-pin Plastic Leaded Chip Carrier. Both share the same commercial temperature rating.
Replacement Considerations
The AD569KN is a direct pin-compatible alternative within the same package material category (plastic), differing only in the specific lead frame configuration. For ceramic packages, the AD569BD offers similar electrical performance but requires thermal consideration for industrial temperatures.
