Overview
The AD7243ANZ is a 12-bit voltage output digital-to-analog converter (DAC) from Analog Devices, packaged in a 16-lead DIP. 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, providing selectable unipolar ranges (0 V to +5 V, 0 V to +10 V) and a bipolar range (±5 V). It features a serial interface with a 300 kHz update rate and includes a clear function for power-on reset.
Feature Summary
- 12-bit resolution with ±1 LSB maximum relative accuracy
- Integrated 5 V internal reference and buffered output amplifier
- Three selectable output ranges: 0–5 V, 0–10 V, and ±5 V
- Serial interface supporting daisy-chaining via SDO
Applications
- Process control systems
- Industrial automation equipment
- Digital signal processing input/output ports
Procurement Notes
Verify the package type matches the required form factor, as the AD7243 series is available in both SOIC and DIP configurations. Confirm the temperature grade corresponds to the application environment, noting that the 'A' and 'B' suffixes indicate industrial range (-40°C to +85°C), while 'S' indicates extended range. Ensure supply voltages align with the specified operating conditions for the selected output range.
Selection Notes
Select the AD7243ANZ when a through-hole DIP package is required for the 12-bit DAC functionality. Choose this part over the SOIC variant if PCB layout constraints necessitate DIP mounting. Verify that the system requires a single-channel DAC with integrated reference capabilities. Consider the settling time of 10 µs and the 300 kHz update rate against system speed requirements.
Part Context
The AD7243 belongs to the DACPORT family of monolithic CMOS data converters. It utilizes Linear Compatible CMOS (LC2MOS) technology to integrate the DAC, reference, and amplifier on a single chip. This design eliminates the need for external trimming components typically required in multi-chip solutions, enhancing reliability and reducing board space.
Replacement Considerations
The AD7243ARZ is a pin-compatible surface-mount alternative offering identical electrical specifications in a 16-SOIC package. For applications requiring extended temperature performance, the AD7243ASZ provides operation from -55°C to +125°C.
