DC812A

DC812A demonstration circuit features the LTC®2606 16bit DAC with I2C interface. This device establishes a new board-density benchmark for 16bit DACs and advances performance standards for output drive and load regulation in single-supply, voltage output DACs. DC812A has many features for evaluating the performance of the LTC2606. Onboard 5V, 4.096V and 2.5V precision references are provided, and the LTC2606 may be powered by the 5V reference for evaluating rail-to-rail operation. Another feature of this board is the onboard LTC2421 20bit ADC for monitoring DAC output voltage. The 16ppm total error of this device is adequate for taking meaningful measurements of various LTC2606 parameters.
