These new, programmable, dual 12-bit and 10-bit digital-to-analog converters (DACs) offer designers high-speed and low power in combination with an easy interface to TI's line of TMS320 digital signal processors (DSPs).

Both the TLC5618 (12-bit) and TLC5617 (10-bit) feature settling-time vs. power consumption programmability (12.5-µs / 3-mW slow mode and 2.5-µs / 8-mW fast mode) and a software programmable power down mode (to 1 µA). They also offer a high-impedance buffered reference input and simultaneous or independent updates of both DACs in the package. Both devices also have a power-on-reset function that ensures repeatable power-up conditions.

The TLC5618 is a 12-bit DAC perfectly suited for applications such as cellular telephones, battery operated industrial controls, remote industrial controls, and machine and motion controls. The 16-bit digital control data is obtained over a 3-wire serial bus that is CMOS compatible.

The TLC5618 and TLC5617 are available in 8-pin SOIC packages.
