Overview
The AD5764BSUZ-REEL7 is a quad, 16-bit digital-to-analog converter (DAC) from Analog Devices. It features bipolar voltage outputs with a nominal full-scale range of ±10 V and operates on supply voltages of ±11.4 V to ±16.5 V. The device guarantees monotonicity with Integral Nonlinearity (INL) of ±2 LSB maximum and Differential Nonlinearity (DNL) of ±1 LSB maximum for the B Grade. Key specifications include a settling time of 10 μs maximum, low noise spectral density of 60 nV/√Hz, and an integrated reference buffer. It utilizes a serial interface compatible with DSP standards.
Feature Summary
- Quad 16-bit resolution with ±2 LSB INL and ±1 LSB DNL
- Bipolar output range: ±10 V nominal, up to ±14 V max
- Integrated reference buffers and programmable short-circuit protection
- Serial interface with clock rates up to 30 MHz
Applications
- Industrial automation
- Open-loop/closed-loop servo control
- Process control
- Data acquisition systems
- Automatic test equipment
Procurement Notes
Verify the specific grade (B Grade) against application requirements for accuracy specifications. Confirm package type is 32-lead TQFP and operating temperature range is −40°C to +85°C. Ensure power supplies match the ±11.4 V to ±16.5 V requirement for analog rails.
Selection Notes
Select this component when high accuracy and simultaneous updating are required. The B Grade offers improved linearity over the C Grade. Consider the AD5764R if an internal voltage reference is preferred to reduce external component count. Verify compatibility with the system's logic voltage levels (2.7 V to 5.25 V).
Part Context
This part belongs to the AD5764 family of high-precision DACs. It is functionally similar to the AD5764CSUZ but with tighter linearity specifications (±2 LSB INL vs ±1 LSB for C Grade). The REEL7 suffix indicates tape and reel packaging. It serves as a bridge between digital control systems and analog actuators in precision applications.
Replacement Considerations
The AD5764CSUZ is a direct pin-compatible alternative with different accuracy grades. The AD5764R includes an internal reference, reducing external components. Check datasheet specifications for INL/DNL differences and reference configuration requirements before substitution.
