The AD7245A/AD7248A is an enhanced version of the industry standard AD7245/AD7248. Improvements include operation from 12 V to 15 V supplies, a ±1/2 LSB linearity grade, faster interface times and better full scale and reference variations with VDD. Additional features include extended temperature range operation for commercial and industrial grades. The AD7245A/AD7248A is a complete, 12-bit, voltage output, digital-to-analog converter with output amplifier and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. Both parts are microprocessor compatible, with high speed data latches and double-buffered interface logic. The AD7245A accepts 12-bit parallel data that is loaded into the input latch on the rising edge of CS or WR. The AD7248A has an 8-bit-wide data bus with data loaded to the input latch in two write operations. For both parts, an asynchronous LDAC signal transfers data from the input latch to the DAC latch and updates the analog output. The AD7245A also has a CLR signal on the DAC latch which allows features such as power-on reset to be implemented. The on-chip 5 V buried Zener diode provides a low noise, tem- perature compensated reference for the DAC. For single supply operation, two output ranges of 0 V to 5 V and 0 V to 10 V are available, while these two ranges plus an additional ±5 V range are available with dual supplies. The output amplifiers are capa- ble of developing 10 V across a 2 kΩ load to GND. The AD7245A/AD7248A is fabricated in linear compatible CMOS (LC2 MOS), an advanced, mixed technology process that combines precision bipolar circuits with low power CMOS logic. The AD7245A is available in a small, 0.3" wide, 24-lead DIP and SOIC and in 28-terminal surface mount packages. The AD7248A is packaged in a small, 0.3" wide, 20-lead DIP and SOIC and in 20-terminal surface mount packages. DACPORT is a registered trademark of Analog Devices, Inc.
