Product Overview
The AD7243 is a complete 12-bit voltage output digital-to-analog converter featuring an integrated output amplifier and Zener voltage reference on a single CMOS chip. This monolithic design eliminates the need for external trims to achieve full specified performance.
Key Features
- 12-bit CMOS DAC with on-chip voltage reference and output amplifier
- Three selectable output ranges: -5V to +5V, 0V to +5V, 0V to +10V
- SPI serial interface with 300 kHz DAC update rate
- Compact 16-lead SOIC package for space-constrained applications
- Excellent linearity: ±1/2 LSB across temperature range
- Low power dissipation: 100 mW typical
- CLR function for power-on reset capability
