AD5755-1ACPZ

Overview

The AD5755-1ACPZ is a quad-channel, 16-bit digital-to-analog converter (DAC) featuring both current and voltage outputs. It operates with analog supplies ranging from −26.4 V to +33 V and digital supplies from 2.7 V to 5.5 V. The device integrates dynamic power control via an on-chip DC-to-DC boost converter, regulating output driver voltage between 7.4 V and 29.5 V to minimize thermal dissipation. Key specifications include ±0.05% maximum total unadjusted error (TUE) for current modes and ±0.04% for voltage modes. It supports HART connectivity through dedicated CHART pins and utilizes a versatile 3-wire serial interface compatible with standard SPI and DSP protocols.

Feature Summary

• Quad-channel 16-bit resolution with guaranteed monotonicity.
• Integrated dynamic power control using a DC-to-DC boost converter for thermal management.
• HART network connectivity enabled by dedicated CHART pins on each channel.
• User-programmable offset and gain with on-chip diagnostics and watchdog timer.

Applications

• Process control systems
• Actuator control loops
• Programmable logic controllers (PLCs)
• HART network connectivity interfaces

Procurement Notes

Verify the specific package variant against the ordering guide, as suffixes may indicate different reel quantities or tape-and-reel configurations. Confirm that the application environment remains within the specified industrial temperature range of −40°C to +105°C. Ensure supply voltages do not exceed absolute maximum ratings to prevent device damage.

Selection Notes

Select this component for applications requiring simultaneous voltage and current output capabilities with high precision. The integrated boost converter makes it suitable for environments where thermal management is critical. Verify compatibility with the host microcontroller's serial interface timing requirements, particularly regarding the 30 MHz clock rate and SYNC pulse widths.

Part Context

The AD5755-1 belongs to the AD5755 family of DACs, which also includes the AD5755 and AD5757. These devices share similar architectural features but may differ in specific output configurations or companion product recommendations. The AD5755-1 is specifically optimized for HART connectivity and dynamic power control in industrial analog output applications.

Replacement Considerations

Companion products listed include the AD5755 and AD5757. Evaluate these alternatives based on specific interface requirements or pinout compatibility if a direct substitute is needed. Ensure that any replacement maintains the required 16-bit resolution and HART connectivity features.
