LTC2622IMS8#PBF

LTC®2622 is a dual 12bit rail-to-rail voltage-output DAC. This part establishes advanced performance standards for output drive, crosstalk and load regulation in single supply, voltage output multiples. It uses a simple SPI/MICROWIRE™ compatible 3-wire serial interface which can be operated at clock rates up to 50MHz. It incorporates a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale, and after powerup, they stay at zero scale until a valid write and update take place. Typical applications include mobile communications, process control and industrial automation, instrumentation and automatic test equipment.
