description

The TLV5627 is a four channel, 8-bit voltage

output digital-to-analog converter (DAC) with a

flexible 4-wire serial interface. The 4-wire serial

interface allows glueless interface to TMS320,

SPI, QSPI, and Microwire serial ports. The

TLV5627 is programmed with a 16-bit serial word

comprised of a DAC address, individual DAC

control bits, and an 8-bit DAC value.

The device has provision for two supplies: one

digital supply for the serial interface (via pins

and DGND), and one for the DACs,

reference buffers and output buffers (via pins AV

and AGND). Each supply is independent of the other, and

can be any value between 2.7 V and 5.5 V. The dual supplies allow a typical application where the DAC will be

controlled via a microprocessor operating on a 3-V supply (also used on pins DV and DGND), with the DACs

operating on a 5-V supply. The digital and analog supplies can be tied together.

The resistor string output voltage is buffered by an x2 gain rail-to-rail output buffer. The buffer features a

Class AB output stage to improve stability and reduce settling time. A rail-to-rail output stage and a power-down

mode make it ideal for single voltage, battery based applications. The settling time of the DAC is programmable

to allow the designer to optimize speed versus power dissipation. The settling time is chosen by the control bits

within the 16-bit serial input string. A high-impedance buffer is integrated on the REFINAB and REFINCD

terminals to reduce the need for a low source impedance drive to the terminal. REFINAB and REFINCD allow

DACs A and B to have a different reference voltage than DACs C and D.

The device, implemented with a CMOS process, is available in 16-terminal SOIC and TSSOP packages. The

TLV5627C is characterized for operation from 0°C to 70°C. The TLV5627I is characterized for operation from

–40°C to 85°C.
