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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.

SLAS269F – MAY 2000 – REVISED NOVEMBER 2008 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.

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.
