APPLICATION INFORMATION
general function
The TLV5613 is a 12-bit, single supply DAC, based on a resistor string architecture. It consists of a parallel
interface, speed and power down control logic, a resistor string and a rail-to-rail output buffer. The output voltage
(full scale determined by reference) is given by:
2REF
CODE
0x1000
[V]
Where REF is the reference voltage and CODE is the digital input value, range 0x000 to 0xFFF. A power on
reset initially puts the internal latches to a defined state (all bits zero).
parallel interface
The device latches data on the positive edge of WE. It must be enabled with CS low. Whether the data is written
to one of the DAC holding latches (MSW, LSW) or the control register, depends on the address bits A1 and A0.
LDAC low updates the DAC with the value in the holding latch. LDAC is an asynchronous input and can be held
low, if a separate update is not necessary. Two more asynchronous inputs, SPD and PWD control the settling
times and the power down mode:
SPD:
Speed control
1
→ fast mode
0
→ slow mode
PWD:
Power control
1
→ normal operation 0 → power down
