Highly accurate low-power, voltage-output quad-channel DACs

Texas Instruments’ DAC80004/70004/60004 (DACx0004) are highly accurate, low-power, voltage-output, quad-channel, 16, 14, 12-bit DACs respectively. The devices are ensured monotonic by design and offer excellent linearity of less than 1LSB (Max). The reference input of the DAC is buffered internally using a dedicated reference buffer. The devices incorporate a power-on-reset circuit that ensures the DAC output powers up at zero scale or mid scale depending on status of the POR pin and remains in this state until a valid code is written to the device. These devices consume very low current of 1mA/channel making them ideal for portable, battery-operated equipment. These devices also contain a power-down feature that reduces current consumption to typically 3µA at 5V. The devices use a versatile four or three-wire serial interface that operates at clock rates up to 50MHz. The devices also include a SDO pin to daisy chain multiple devices. The interface is compatible with standard SPI, QSP, Microwire, and DSP interfaces. The devices are offered in easy-to-assemble 14-pin TSSOP packages or an ultra small 14-pin VSON package and are fully specified over the extended industrial temperature range of –40C to 125C.
