AD5627RBRMZ-1REEL7 - 12-Bit nanoDAC+™ Digital-to-Analog Converter with I²C Interface
1. Overview
The AD5627RBRMZ-1REEL7 is a dual 12-bit nanoDAC with an on-chip 2.5V, 5ppm/°C reference voltage source and an I²C-compatible interface. It operates from a single 2.7V to 5.5V power supply and features guaranteed monotonicity, per-channel power-down capability, and hardware LDAC (load DAC) and CLR (clear) functions. The device supports I²C standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes, making it suitable for applications such as process control, data acquisition systems, and portable battery-powered instruments.
2. Key Features
Key features include a power-on reset circuit that ensures the DAC output starts at 0V, low power consumption ideal for battery-operated devices, and an on-chip precision output amplifier that enables rail-to-rail output swing. The device is available in a 10-lead MSOP package and is designed for industrial and automotive applications with a temperature range of -40°C to +105°C.
3. Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Digital gain and offset adjustment
- Programmable voltage/current sources
4. Design Considerations & Alternative Models
· Reference Selection. For highest accuracy, use external reference in precision applications. Internal reference suitable for most general-purpose applications
· PCB Layout. Place decoupling capacitors close to VDD and REF pins. Minimize digital trace lengths near analog outputs, Use ground plane for noise reduction.
· Power Sequencing. No specific power sequencing requirements, and Power-down mode reduces current to 0.3µA (typical).
· AD5627RBRMZ-2REEL7: 2.5V internal reference version
· AD5628R: Dual-channel version
· AD5667R: 16-bit resolution version
5. Conclusion
The AD5627RBRMZ-1REEL7 combines 12-bit precision, ultra-low power operation, and small form factor in a single-chip DAC solution. Its integrated reference, flexible I²C interface, and excellent DC performance make it particularly suitable for space-constrained, battery-powered applications.
