New 10-bit serial DAC features high-speed and low-power operation TI has announced the TLC5615, a 10-bit serial digital-to-analog converter (DAC) that provides high performance in a small package, along with a CMOS-compatible three-wire interface for easy interfacing with TMS320 DSPs. The TLC5615 DAC features an update rate of 1.21 MHz when operating at a clock speed of 20 MHz and a settling time of 12.5 ms (to 0.5 LSB), while consuming only 1.75 mW of power (maximum). It also features single-supply 5-V operation, a high-impedance reference input, a maximum integral nonlinearity (INL) of ±1 LSB, a maximum differential nonlinearity (DNL) of ±0.9 LSB ensuring monotonicity over the temperature range. The output amplifier has a gain of 2, therefore the 16-bit digital control word determines a 10-bit analog output ranging between 0 and a nominal full-scale value of two times the input reference voltage. The TLC5615 is offered in a small eight-pin, small outline IC (SOIC) package or a regular eight-pin, plastic dual-in-line (PDIP) package, and is available in commercial (0°C to 70°C) and industrial (-40°C to 85°C) temperature ranges In addition to the CMOS three-wire interface, an additional digital output enables daisy chaining of multiple TLC5615s or data read-back to the processor (four-wire communication). Supported communications protocols include the SPI, QSPI, and Microwire standards. Typical applications for the TLC5615 include digital offset and gain adjustment, remote industrial controls, motion-control devices, cellular telephones, and battery powered test instruments. Suggested resale pricing for the TLC5615 is US $2.90 in quantities of 1,000. For more information, see the TLC5615 DAC data sheet.
