AD5662BRJZ-1500RL7

Overview

The AD5662BRJZ-1500RL7 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 features rail-to-rail output capability. The device guarantees 12-bit accuracy and monotonicity by design. Key electrical parameters include a maximum settling time of 10 μs, a typical power consumption of 250 μA at 5 V, and power-down currents as low as 480 nA. It utilizes a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 30 MHz.

Feature Summary

• 16-bit resolution with guaranteed 12-bit accuracy and monotonic operation
• Rail-to-rail output amplifier allowing full-scale swing from 0 V to VDD
• Low power consumption: 250 μA active current; 480 nA in power-down mode at 5 V
• Power-on reset circuit configurable to zero scale or midscale output

Applications

• Process control systems
• Portable battery-powered instruments
• Programmable voltage and current sources
• Digital gain and offset adjustment circuits

Procurement Notes

Verify that the suffix '1500RL7' corresponds to the specific reel quantity and tape-and-reel packaging configuration required for automated assembly. Confirm that the 'B' grade designation meets the relative accuracy specifications (±32 LSB max) necessary for the target application environment.

Selection Notes

Select this component when a single-channel, high-resolution DAC is needed in a compact SOT-23 package. Ensure the system requires an external reference voltage, as the AD5662 does not integrate an internal reference. Verify that the 3-wire serial interface timing aligns with the host microcontroller's capabilities, particularly regarding the 30 MHz maximum clock rate.

Part Context

The AD5662 belongs to Analog Devices' nanoDAC family, designed for space-constrained applications. The BRJZ variant indicates the B-grade performance level and the SOT-23-8 package type. This part serves as a low-cost, low-power alternative to larger packages while maintaining precision suitable for industrial and portable instrumentation.

Replacement Considerations

The AD5662ARJZ-2 is a functional substitute offering similar specifications but with a power-on reset to midscale instead of zero scale. Both parts share the same pinout and serial interface protocol.
