APPLICATION INFORMATION
TLV5627 interfaced to MCS51 microcontroller
hardware interfacing
Figure 18 shows an example of how to connect the TLV5627 to an MCS51 Microcontroller. The serial DAC
input data and external control signals are sent via I/O Port 3 of the controller. The serial data is sent on the RxD
line, with the serial clock output on the TxD line. Port 3 bits 3, 4, and 5 are configured as outputs to provide the
DAC latch update (LDAC), chip select (CS) and frame sync (FS) signals for the TLV5627. The active low power
down pin (PD) of the TLV5627 is pulled high to ensure that the DACs are enabled.

linearity, offset, and gain error using single ended supplies
When an amplifier is operated from a single supply, the voltage offset can still be either positive or negative. With
a positive offset, the output voltage changes on the first code change. With a negative offset, the output voltage
may not change with the first code, depending on the magnitude of the offset voltage.
The output amplifier attempts to drive the output to a negative voltage. However, because the most negative
supply rail is ground, the output cannot drive below ground and clamps the output at 0 V.
The output voltage then remains at zero until the input code value produces a sufficient positive output voltage
to overcome the negative offset voltage, resulting in the transfer function shown in Figure 19.
