12-Bit/10-Bit/8-Bit Voltage Output DAC Family Integrates Internal Reference in Tiny SC70 Package
The low-power LTC2630 draws only 160uA of supply current at 3V and 180uA at 5V. Communicating via a 3-wire SPI-compatible serial interface at clock rates up to 50MHz, the LTC2630 DAC output settles for a half-scale step in less than 5us. Operating from a single 2.7V to 5.5V supply, the output can swing to the internal reference voltage or rail-to-rail to the supply voltage. The DAC outputs can power up to zero-scale or mid-scale, allowing more flexibility for designs that cannot be forced to ground when power is first applied.
The LTC2630-12, LTC2630-10, and LTC2630-8 are pin-compatible 12-bit, 10-bit, and 8-bit DACs, respectively. They are all available today in 6-pin SC70 packages, offering a pin- and software-compatible family for performance/cost optimization.
