APPLICATION INFORMATION
The offset error, not the linearity error, produces this breakpoint. The transfer function would have followed the
dotted line if the output buffer could drive below the ground rail.
For a DAC, linearity is measured between zero input code (all inputs 0) and full scale code (all inputs 1) after
offset and full scale are adjusted out or accounted for in some way. However, single supply operation does not
allow for adjustment when the offset is negative due to the breakpoint in the transfer function. So the linearity
is measured between full scale code and the lowest code that produces a positive output voltage.
TLV5633 interfaced to an Intel MCS
51 controller
The circuit in Figure 15 shows how to interface the TLV5633 to an Intel MCS
51 microcontroller. The address
bus and the data bus of the controller are multiplexed on port 0 (non page mode) to save port pins. To separate
the address bits and the data bits, the controller provides a dedicated signal, address latch enable (ALE), which
is connected to a latch at port 0.
An address decoder is required to generate the chip select signal for the TLV5633. In this example, a simple
3-to-8 decoder (74AC138) is used for the interface as shown in Figure 15. The DAC is memory mapped at
addresses 0x8000/1/2/3 within the data memory address space and mirrored every 32 address locations
(0x8020/1/2/3, 0x8040/1/2/3, etc.). In a typical microcontroller system, programmable logic should be used to
generate the chip select signals for the entire system.
The data pins and the WE pin of the TLV5633 can be connected directly to the multiplexed address and data
bus and the WR signal of the controller.
The application uses the TLV5633 device’s internal reference at 2.048 V. The LDAC pin is connected to P3.5
and is used to update the DAC after both data bytes have been written.
