description
The TLC7226C and TLC7226E consist of four 8-bit voltage-output digital-to-analog converters (DACs) with
output buffer amplifiers and interface logic on a single monolithic chip.
Separate on-chip latches are provided for each of the four DACs. Data is transferred into one of these data
latches through a common 8-bit TTL /CMOS-compatible 5-V 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 DAC includes an output buffer amplifier capable of sourcing up to 5 mA of output current.
The TLC7226 performance is specified for input reference voltages from 2 V to VDD – 4 V with dual supplies.
The voltage mode configuration of the DACs allows the TLC7226 to be operated from a single power supply
rail at a reference of 10 V.
The TLC7226 is fabricated in a LinBiCMOS
process that has been specifically developed to allow high-speed
digital logic circuits and precision analog circuits to be integrated on the same chip. The TLC7226 has a common
8-bit data bus with individual DAC latches. This provides a versatile control architecture for simple interface to
microprocessors. All latch-enable signals are level triggered.
Combining four DACs, four operational amplifiers, and interface logic into either a 0.3-inch wide, 20-terminal
dual-in-line IC (DIP) or a small 20-terminal small-outline IC (SOIC) allows a dramatic reduction in board space
requirements and offers increased reliability in systems using multiple converters. The pinout is aimed at
optimizing board layout with all of the analog inputs and outputs at one end of the package and all of the digital
inputs at the other.
The TLC7226C is characterized for operation from 0
°C to 70°C. The TLC7226E is characterized for operation
from – 25
°C to 85°C.
