AD5760ACPZ-REEL7

Overview

The AD5760ACPZ-REEL7 is a true 16-bit, unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features ±0.5 LSB integral nonlinearity (INL) and operates on bipolar supplies up to ±16.5 V. The device accepts reference inputs ranging from 5 V to VDD − 2.5 V and VSS + 2.5 V to 0 V. Key electrical parameters include an 8 nV/√Hz output noise spectral density, a gain error temperature coefficient of ±0.018 ppm/°C, and a 2.5 µs settling time for a 10 V step. It utilizes a 35 MHz Schmitt-triggered serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.

Feature Summary

• True 16-bit resolution with ±0.5 LSB maximum INL and guaranteed monotonicity.
• Wide power supply range supporting up to ±16.5 V for flexible output spans.
• Ultra-low noise performance with 8 nV/√Hz spectral density and 3.5 nV-sec midscale glitch impulse.
• Integrated precision reference buffers and power-on reset logic ensuring 0 V startup.

Applications

• Medical instrumentation
• Test and measurement equipment
• Industrial control systems
• Scientific and aerospace instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific grade (A or B) required for your application, as INL and DNL specifications differ between versions. Confirm that the REEL7 suffix indicates tape-and-reel packaging suitable for automated assembly. Ensure the operating environment stays within the -40°C to +125°C industrial temperature range to maintain rated performance.

Selection Notes

Select this component when high linearity and low drift are critical. The A-grade version offers ±2 LSB INL, while the B-grade provides ±0.5 LSB. Consider external buffering if higher drive current is needed, as the DAC output is unbuffered. Verify that the reference voltage requirements fit within the specified input ranges relative to the analog supply rails.

Part Context

The AD5760 belongs to Analog Devices' family of high-precision DACs, positioned alongside the AD5780 (18-bit) and AD5790/AD5791 (20-bit). It serves as a cost-effective solution for applications requiring 16-bit accuracy without the complexity of higher-resolution parts. The LFCSP package allows for compact PCB layouts in dense industrial designs.

Replacement Considerations

For direct pin-compatible upgrades requiring higher resolution, consider the AD5781 (18-bit, 0.5 LSB INL). For lower cost applications where ±2 LSB INL is acceptable, the AD5760 A-grade variant covers the same footprint. Check companion products like the AD8675 for output buffering needs.
