Linear Technology Corporation introduces the LTC2605, an octal 16-bit voltage output DAC with an I2C serial interface in a 16-pin SSOP package — the same board area as an SO-8. The device's guaranteed monotonic performance, small size and low power make it well suited for digital calibration, trim/adjust and level setting applications in a wide variety of products. The LTC2605's output buffers deliver desirable drive capability over their entire 2.7 V to 5.5 V supply voltage range. The DAC outputs directly drive capacitive loads up to 1000 pF or current loads up to 15 mA and maintain good linearity to within millivolts of VCC or ground. In addition, low output voltage noise (15µVp-p) reduces the need for output filtering. A full-scale transition on seven of the eight DACs causes < 10µV change in the eighth DAC, effectively eliminating crosstalk as a source of error.
