LTC2641IMS8-14#PBF

LTC2641 is a 12bit unbuffered voltage output DAC. This DAC operate from a single 2.7 to 5.5V supply and it is guaranteed monotonic over temperature. It provides 16bit performance (±1LSB INL and ±1LSB DNL) over temperature. Unbuffered DAC outputs result in low supply current of 120µA and a low offset error of ±1LSB. It features a reference input range of 2V to VDD. It uses a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz and can interface directly with optocouplers for applications requiring isolation. A power-on reset circuit clears the LTC2641’s DAC output to zero scale. A logic low on the CLR (active high) pin asynchronously clears the DAC to zero scale. This DAC is all specified over the commercial and industrial ranges. Application includes high resolution offset and gain, adjustment, process control and industrial automation, automatic test equipment, data acquisition systems.
