APPLICATION INFORMATION
general function
The TLV5624 is an 8-bit, single supply DAC, based on a resistor string architecture. It consists of a serial
interface, a speed and power-down control logic, a programmable internal reference, a resistor string, and a
rail-to-rail output buffer.
The output voltage (full scale determined by reference) is given by:
2 REF0x1000[V]
Where REF is the reference voltage and CODE is the digital input value in the range 0x000 to 0xFF0. Bits 3
to 0 must be set to 0. A power on reset initially puts the internal latches to a defined state (all bits zero).
serial interface
The device has to be enabled with CS set to low. A falling edge of FS starts shifting the data bit-per-bit (starting
with the MSB) to the internal register on high-low transitions of SCLK. After 16 bits have been transferred or
FS rises, the content of the shift register is moved to the DAC latch, which updates the voltage output to the new
level.
The serial interface of the TLV5624 can be used in two basic modes:
Four wire (with chip select)
Three wire (without chip select)
Using chip select (four-wire mode), it is possible to have more than one device connected to the serial port of
the data source (DSP or microcontroller). Figure 13 shows an example with two TLV5624s connected directly
to a TMS320 DSP.
