The AD5064BRUZ is an Analog Devices quad-channel, 16-bit, buffered voltage-output nanoDAC® with an SPI serial interface, packaged in a 16-lead TSSOP and qualified over the industrial −40 °C to +125 °C range. Fabricated on a low-power CMOS process, it provides ±1 LSB INL accuracy, rail-to-rail output operation from a single 4.5 V to 5.5 V supply, an on-chip reference buffer and output amplifier, and supports clock speeds up to 50 MHz with power-on reset to zero-scale or midscale—making it a fully integrated, precision, four-channel analog output solution.
Key Features & Benefits
● Internal Reference Buffer and Output Amplifier: Eliminates external op-amps while still driving 5 kΩ loads with 0.5 Ω DC output impedance.
● Rail-to-Rail Output Operation: Output swings from 0 V to VDD, maximizing usable dynamic range in single-supply 5 V systems.
● High-Speed 50 MHz SPI Interface: The 3-wire Schmitt-trigger serial interface is compatible with standard SPI, QSPI, MICROWIRE, and DSP buses, with daisy-chain capability via SDO.
● Flexible Reference Configuration: Per-channel independent references, or a common shared reference with 120 kΩ input impedance and 2.5 V to VDD input range.
● Power-On Reset and CLR Function: DAC outputs power up to zero-scale or midscale with low glitch, and the CLR pin forces outputs to a user-programmed code.
● Per-Channel Power-Down to 400 nA: Three selectable power-down modes with programmable output termination preserve battery life in portable instruments.
● 5.8 µs Settling to ±0.5 LSB: Fast full-scale voltage settling time supports dynamic waveform generation and closed-loop control updates.
Typical Applications
The AD5064BRUZ is a mainstay in industrial process control, where its four channels generate programmable setpoints, loop offsets, and bias voltages for PID controllers and actuator drivers. In data acquisition systems, it serves as a multi-channel analog output module for calibration signal generation, programmable voltage and current sources, and digital gain and offset adjustment in sensor signal chains. Portable battery-powered instruments exploit the 400 nA power-down mode and single 5 V rail, while programmable attenuators, optical module bias control, and galvanically isolated interfaces benefit from the 50 MHz SPI daisy-chain capability.
Frequently Asked Questions
Q: Can the four channels use different reference voltages?
A: Yes. The individual-reference option provides a dedicated VREF pin per DAC, allowing each channel a unique full-scale span from 2.5 V to VDD.
Q: How fast does the output settle?
A: Settling time to ±0.5 LSB after a full-scale code change is typically 5.8 µs, supporting update rates near 125 kSPS.
