GENERAL DESCRIPTIO N
The A D7226 contains four 8-bit voltage-output digital-to-analog converters,with output buffer amplifiers and interface logic on a single monolithic chip. No external trim s are required to achieve full specified performance for the part.
Separate on-chip latches are provided for each of the four D/A converters. Data is transferred into one of these data latches through a common 8-bit TTL/CMOS (5V) compatible input port. Control inputs A0 and A1 determine which DAC is loaded when WR goes low. The control logic is speed-compatible with most 8-bit microprocessors.
Each D/A converter includes an output buffer amplifier capable of driving up to 5mA of output current. The amplifiers' offsets are laser-trimmed during manufacture, thereby eliminating any requirement for offset nulling.
Specified performance is guaranteed for input reference voltages from +2V to + 12.5V with dual supplies. The part is also specified for single supply operation at a reference of +10V.
The AD7226 is fabricated in an all ion-implanted high speed Linear Compatible CMOS (LC2MOS) process which has been specifically developed to allow high speed digital logic circuits and precision analog circuits to be integrated on the same chip.
PRODUCT HIGHLIGHTS
1. DAC-to-DAC Matching
Since all four DACs are fabricated on the same chip at the same time, precise matching and tracking between the DACs is inherent.
2. Single Supply 0peration
The voltage mode configuration of the DACs allows the AD7226 to be operated fro m a single power supply rail.
3. M icroprocessor Compatibility
The AD7226 has a common 8-bit data bus with individual DAC latches, providing a versatile control architecture for simple interface to microprocessors. All latch enable signals are level triggered.
4. Small Size
Combining four DACs and four opamps plus interface logic into a 20-pin DIP or S0IC or a 20-ter minal surface mount package allows a dramatic reduction in board space require-ments and offers increased reliability in systems using multiple converters. Its pinout is aimed at optimizing board layout with all the analog inputs and outputs at one end of the package and all the digital inputs at the other.
