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
DVDD and DGND), and one for the DACs,
reference buffers and output buffers (via pins AVDD 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 DVDD 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.
