DESCRIPTION
The TLV5610, TLV5608, and TLV5629 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.
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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) IDD is measured while continuously writing code 2048 to the DAC. For VIH < DVDD - 0.7 V and VIL > 0.7 V, supply current increases.
(2) Power supply rejection ratio at full scale is measured by varying AVDD and is given by:
PSRR = 20 log [(EG(AVDDmax) - EG(AVDDmin))/VDDmax]
