Overview
The AD7243BRZ-REEL is a 12-bit voltage output digital-to-analog converter (DAC) from Analog Devices, packaged in a 16-lead SOIC. It integrates an on-chip Zener voltage reference and a buffered output amplifier capable of driving +10 V across a 2 kΩ load. The device supports single or dual supply operation with analog power ranges of +10.8 V to +16.5 V for VDD and -10.8 V to -16.5 V for VSS. Key electrical specifications include a settling time of 10 µs maximum, differential nonlinearity of ±0.9 LSB, and integral nonlinearity of ±0.5 LSB. It features a 3-wire serial interface supporting up to 300 kHz update rates.
Feature Summary
- Integrated 12-bit DAC with on-chip 5 V Zener reference and buffered output amplifier
- Three selectable output voltage ranges: 0 V to +5 V, 0 V to +10 V, and ±5 V
- Serial interface compatible with DSPs and microcomputers, supporting daisy-chaining via SDO
- Low power dissipation of 100 mW typical with 10 mA max supply current
Applications
- Process control systems
- Industrial automation equipment
- Digital signal processing input/output ports
Procurement Notes
Verify the REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm the B grade designation corresponds to the specified industrial temperature range of -40°C to +85°C. Ensure the SOIC-16 package footprint matches the target PCB design constraints.
Selection Notes
Select this component for applications requiring a complete monolithic 12-bit DAC solution without external trimming. Choose the bipolar ±5 V configuration only if dual supplies are available. Verify that the required output swing does not exceed the amplifier's capability of +10 V across a 2 kΩ load.
Part Context
This part belongs to the AD7243 DACPORT family, which utilizes Linear Compatible CMOS (LC2MOS) technology. The BRZ suffix denotes the RoHS-compliant SOIC package variant. Other variants in the series include DIP packages and different temperature grades such as the AD7243BNZ.
Replacement Considerations
The AD7243BR-REEL is listed as obsolete with the AD7243BRZ identified as a parametric equivalent replacement. Verify pin compatibility and electrical specifications before substitution.
