Overview
The AD5662ARM-1 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7 V to 5.5 V supply with typical current consumption of 250 μA at 5 V. The device features rail-to-rail output swing and an external reference input. It includes a power-on reset circuit that initializes the output to zero scale for the '-1' suffix variant. The DAC utilizes a 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz. It is housed in an 8-lead MSOP package.
Feature Summary
- 16-bit resolution with guaranteed monotonicity by design
- Rail-to-rail output amplifier with 2 kΩ load capability
- Power-on reset to zero scale (AD5662x-1)
- Three software-selectable power-down modes reducing current to 480 nA @ 5 V
Applications
- Process control systems
- Portable battery-powered instruments
- Programmable voltage and current sources
- Digital gain and offset adjustment circuits
Procurement Notes
Verify the specific ordering suffix 'ARM-1' against the manufacturer's official ordering guide to confirm the package type (MSOP) and power-on reset behavior (zero scale). Ensure compatibility with the required serial interface timing specifications before procurement.
Selection Notes
Select this component when a low-power, high-resolution single-channel DAC is required for battery-operated devices. The external reference requirement allows flexibility in setting output ranges. Verify that the 10 μs settling time meets system speed requirements.
Part Context
The AD5662 belongs to the nanoDAC family, designed for low-power applications. The '-ARM' suffix indicates the 8-lead MSOP package, while the '-1' suffix specifies the power-on reset state as zero scale. This distinguishes it from variants like the AD5662ARJZ-2REEL7 which resets to midscale.
Replacement Considerations
The AD5662ARMZ-1 is a direct equivalent offering the same electrical characteristics and zero-scale power-on reset in the MSOP package. Check for automotive qualified versions if operating conditions require extended temperature reliability.
