DESCRIPTION  
The TLV5630, TLV5631, and TLV5632 are pin-compatible, eight-channel, 12-/10-/8-bit voltage output DACs  
each with a flexible serial interface. The serial interface allows glueless interface to TMS320 and SPI, QSPI, and  
Microwire serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits.  
Additional features are a power-down mode, an LDAC input for simultaneous update of all eight DAC outputs,  
and a data output which can be used to cascade multiple devices, and an internal programmable band-gap  
reference.  
The resistor string output voltage is buffered by a rail-to-rail output amplifier with a programmable settling time to  
allow the designer to optimize speed vs power dissipation. The buffered, high-impedance reference input can be  
connected to the supply voltage.  
Implemented with a CMOS process, the DACs are designed for single-supply operation from 2.7 V to 5.5 V, and  
can operate on two separate analog and digital power supplies. The devices are available in 20-pin SOIC and  
TSSOP packages.

APPLICATION INFORMATION  
GENERAL FUNCTION  
The TLV5630/31/32 are 8-channel, single-supply DACs, based on a resistor string architecture. They consist of a  
serial interface, a speed and power-down control logic, an internal reference, a resistor string, and a rail-to-rail  
output buffer.  
The output voltage (full scale determined by reference) for each channel is given by:  
CODE  
0x1000  
2REF  
[V]  
where REF is the reference voltage and CODE is the digital input value. The input range is 0x000 to 0xFFF for  
the TLV5630, 0x000 to 0xFFC for the TLV5631, and 0x000 to 0xFF0 for the TLV5632.  
POWER ON RESET (POR)  
The built-in power-on-reset circuit controls the output voltage after power up. On power up, all latches including  
the preset register are set to zero, but the DAC outputs are only set to zero if the LDAC is low. The DAC outputs  
may have a small offset error produced by the output buffer. The registers remains at zero until a valid write  
sequence is made to the DAC, changing the DAC register data. This is useful in applications where it is  
important to know the state of the outputs of the DAC after power up. All digital inputs must be logic low until the  
digital and analog supplies are applied. Any logic high voltages applied to the logic input pins when power is not  
applied to AVDD and DVDD, may power the device logic circuit through the overvoltage protection diode causing  
an undesired operation. When separate analog (AVDD) and digital (DVDD) supplies are used, AVDD must come up  
first before DVDD, to ensure that the power-on-reset circuit operates correctly.  
SERIAL INTERFACE  
A falling edge of FS starts shifting the data on DIN starting with the MSB to the internal register on the falling  
edges of SCLK. After 16 bits have been transferred, the content of the shift register is moved to one of the DAC  
holding registers, depending on the address bits within the data word. A logic 0 on the LDAC pin is required to  
transfer the content of the DAC holding register to the DAC latch and to update the DAC outputs. LDAC is an  
asynchronous input. It can be held low if a simultaneous update of all eight channels is not needed.  
For daisy-chaining, DOUT provides the data sampled on DIN with a delay of 16 clock cycles.

Difference between DSP mode (MODE = N.C. or 0) and µC (MODE = 1) mode:  
In µC mode, FS needs to be held low until all 16 data bits have been transferred. If FS is driven high before  
the 16th falling clock edge, the data transfer is cancelled. The DAC is updated after a rising edge on FS.  
In DSP mode, FS needs to stay low for 20 ns and can go high before the 16th falling clock edge.  
In DSP mode there needs to be one falling SCLK edge before FS goes low to start the write (DIN) cycle. This  
extra falling SCLK edge has to happen at least 5 ns before FS goes low, tsu(CK-FS) 5 ns.  
In µC mode, the extra falling SCLK edge is not necessary. However, if it does happen, the extra negative  
SCLK edge is not allowed to occur within 10 ns after FS goes HIGH to finish the WRITE cycle (tsu(FS-C17)).

DAC A-H AND TWO-CHANNEL REGISTERS  
Writing to DAC A-H sets the output voltage of channel A-H. It is possible to automatically generate the  
complement of one channel by writing to one of the four two-channel registers (DAC A and B etc.).  
The TLV5630 decodes all 12 data bits. The TLV5631 decodes D11 to D2 (D1 and D0 are ignored). The TLV5632  
decodes D11 to D4 (D3 to D0 are ignored).  
PRESET  
The outputs of the DAC channels can be driven simultaneously to a predefined value stored in the preset register  
by driving the PRE input pin low and asserting the LDAC input pin. The preset register is cleared (set to zero) by  
the POR circuit after power up. Therefore, it must be written with a predefined value before asserting the PRE  
pin low, unless zero is the desired preset value. The PRE input is asynchronous to the clock.

In power-down mode, the amplifiers of the selected DAC pair are disabled and the total power consumption of  
the device is significantly reduced. Power-down mode of a specific DAC pair can be selected by setting the PXY  
bit within the data word to 1.  
There are two settling time modes: fast and slow. Fast mode of a DAC pair is selected by setting SXY to 1 and  
slow mode is selected by setting SXY to 0.

REFERENCE  
The DAC reference can be sourced internally or externally by programming bits D2 (R1) and D1 (R0) of the  
CTRL0 register (address = 08h). If an external source of reference is applied to the REF pin, the device must be  
configured to accept the external reference source by setting R1 and R0 to 00 or 01. If R1 and R0 is set to select  
for internal reference, a voltage of 1.024 V (if R1 and R0 = 10) or 2.048 V (if R1 and R0 = 11) is available. The  
internal reference can source up to 1 mA, therefore. it can be used as an external system reference. A  
decoupling capacitor must be connected to the REF pin if internal reference is selected to ensure output stability.  
A 1 µF to 10 µF capacitor in parallel to a 100 pF capacitor should be sufficient, see Figure 13.

BUFFERED AMPLIFIER  
The DAC outputs are buffered by an amplifier with a gain of two, which are configurable as Class A (fast mode)  
or Class AB (slow or low-power mode). The output buffers have near rail-to-rail output with short-circuit  
protection, and can reliably drive a 2-kload with a 100-pF load capacitance.
