TI debuts 16-bit quad DAC for low-power process control, portable instrumentation
Tucson, AZ—Texas Instruments Inc. (TI, Dallas, TX) recently launched a 16-bit quad digital-to-analog converter (DAC) as part of its Burr-Brown product line.
Tucson, AZ— Texas Instruments Inc. n cost. The low-cost data converter is reportedly ideal for portable, low-power systems, such as industrial process control, portable instrumentation, closed-loop monitoring and control, data acquisition and PC peripherals.
DAC8534 uses one 2.7 V- to 5.5 V-power supply, and consumes only 950 uA of power at 5 V. The device also offers a per-channel power-down mode, accessed over a flexible serial interface, which reduces maximum supply current to 1uA. A power-on reset circuit ensures that the DACs power up at zero volts and remain there until a valid write occurs.
'DAC8534 stands alone in the industry as the smallest, lowest-power, quad-channel, 16-bit DAC. By reducing package size and cost by 66% versus the nearest competition, TI has established a new price/performance point in the DAC market,' says David Russell, strategic marketing engineer for TI's DAC products.
DAC8534 features true 16-bit monotonic performance, 10us settling time within
Each on-chip precision output amplifier allows rail- to-rail output performance. The device uses a three-wire serial interface compatible with standard SPI, QSPI, and Microwire interfaces, as well as TI's TMS320 DSP family. It is capable of clock frequencies up to 30MHz and supports simultaneous or sequential output channel updating of up to 16 channels.
