Overview
The AD5662ARJZ-2500RL7 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single 2.7 V to 5.5 V supply and requires an external reference voltage. The device features a power-on reset circuit that initializes the output to midscale upon power-up. It incorporates a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz. The part guarantees 16-bit monotonicity by design and offers low power consumption of 250 μA in normal mode, reducing to 480 nA in power-down modes.
Feature Summary
- 16-bit resolution with guaranteed 12-bit accuracy and rail-to-rail output swing
- Power-on reset to midscale for AD5662x-2 variants
- Three software-selectable power-down modes with current as low as 100 nA at 3 V
- 3-wire serial interface with Schmitt-triggered inputs operating up to 30 MHz
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Digital gain and offset adjustment circuits
- Programmable voltage and current sources
Procurement Notes
Verify the specific suffix '2500' against the manufacturer's official ordering guide to confirm the power-on reset behavior and temperature grade. Ensure the external reference voltage source meets the input range requirements specified in the datasheet. Confirm package availability matches the SOT-23-8 form factor indicated by the RJZ designation.
Selection Notes
Select this component when a single-channel, high-resolution DAC with low power consumption is required. The AD5662ARJZ-2500RL7 is suitable for applications needing a midscale power-on reset state. Consider the external reference requirement if internal references are not available in other family members. Verify that the 3-wire serial interface timing constraints align with the host microcontroller or DSP capabilities.
Part Context
The AD5662 belongs to Analog Devices' nanoDAC family, which focuses on low-power, small-footprint data converters. This specific part number denotes the A-grade version in an SOT-23-8 package with a reel quantity of 2500 units. It shares architectural similarities with the AD5660 but differs in having an external reference input rather than an internal one.
Replacement Considerations
The AD5662BRJZ-2500RL7 is a B-grade alternative with tighter accuracy specifications. The AD5662ARJZ-2REEL7 is a similar variant packaged in reels of 3000 units.
