AD5024/AD5044/AD5064 are low power quad 12-/14-/16-bit VOUT nanoDACs pin compatible and performance upgrade to AD5666 with 4.5 V to 5.5 V power supply, with zero scale or midscale reset, support SDO daisy-chaining function.
The AD5024/AD5044/AD5064 series are low‑power quad 12‑/14‑/16‑bit buffered voltage‑output nanoDACs that operate from a 4.5 V to 5.5 V supply. They feature rail‑to‑rail operation, individual or common reference pins, and a high‑speed serial interface compatible with SPI, QSPI, MICROWIRE and DSP standards. The devices include built‑in reference buffers, output amplifiers, power‑on reset to zero‑scale or mid‑scale, and multiple power‑down modes.
The handbook provides functional block diagrams, pin configurations, absolute maximum ratings, timing characteristics, AC performance data, and an ordering guide. It also lists typical applications such as process control, data‑acquisition systems, portable instruments, programmable voltage sources and attenuators.
| Resolution | 16 bits (AD5064/AD5064‑1) |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V |
| Maximum Serial Clock Frequency | 50 MHz |
| Power‑Up Reset Behavior | Outputs reset to zero scale or midscale until a valid write |
| Power‑Up Time | 45 µs |
| Total Unadjusted Error | < 2 mV |
The AD5064 operates from a 4.5 V to 5.5 V supply.
The serial clock can run up to 50 MHz.
The series provides a quad‑channel configuration, i.e., four independent DAC channels.
When powered on, the reset forces all four DAC outputs to either zero scale or midscale until a valid write command is received.
