Features and Benefits
- Low power quad nanoDACs: 16 Bits
- Relative Accuracy: ±12 LSBs max
- Guaranteed monotonic by design
- 10-lead MSOP and 3mm × 3mm LFCSP_WD package
- 2.7 V to 5.5 V power supply
- Power-on reset to zero
- Per channel power-down
- Serial interface, up to 50MHz
The AD5624 / AD5664, members of the nanoDAC® family, are low power, quad, 12-, 16-bit buffered voltage-out DACs that operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design.
The AD5624 / AD5664 require an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. The parts contain a power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode.
The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 2.25 mW at 5 V, going down to 2.4 μW in power-down mode.
The AD5624 / AD5664 on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5624/AD5664 use a versatile 3-wire serial interface that operates at clock rates up to 50 MHz, and are compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
- Relative accuracy: ±12 LSBs maximum.
- Available in 10-lead MSOP and 10-lead, 3 mm × 3 mm, LFCSP_WD.
- Low power, typically consumes 1.32 mW at 3 V and 2.25 mW at 5 V.
- Maximum settling time of 4.5 μs (AD5624) and 7 μs (AD5664).
- Process control
- Data acquisition systems
- Portable battery-powered instruments
- Digital gain and offset adjustment
- Programmable voltage and current sources
- Programmable attenuators
Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The EVAL-AD5664REBZ (Cypress based) is no longer available. Please use EVAL-AD5664RDBZ (SDP based).
The EVAL-AD5664RDBZ evaluation board helps users quickly prototype new AD5664R circuits and reduce design time. The AD5664R operates from a single 2.7 V to 5.5 V supply.
For full data, see the AD5664R data sheet, which must be used in conjunction with user guide UG-986 when using the EVALAD5664RDBZ evaluation board.
The EVAL-AD5664RDBZ evaluation board interfaces to the USB port of a PC via the SDP-B controller board. Software that allows users to program the AD5664R can be downloaded via the EVAL-AD5664RDBZ product page.
The EVAL-AD5664RDBZ evaluation board requires the EVALSDP-CB1Z board (SDP-B controller board).
Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
