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. The
devices are available in 20-pin SOIC and TSSOP packages.
