LTC2635CUD-HMI10 Quad 10-Bit 4.096V Precision I2C DAC 16-Lead QFN Integrated Circuit Chip

The LTC2635CUD-HMI10 is a quad 10-bit voltage output digital to analog converter from the LTC2635 series, supplied in a 16-Lead QFN package. Four buffered outputs and a 4.096 V internal reference are integrated, which cuts the part count of multi-channel control cards.

On the LTC2635CUD-HMI10 the reference is trimmed to 10 ppm per degree C, and the C grade linearity is specified over the full 10-bit code range. Each channel is monotonic, and the four outputs are matched closely enough for ratiometric control loops. This is the linearity bin published for the LTC2635.

Data is written through the I2C port into double-buffered latches, so channels can be loaded and then updated together or independently. Power-on reset places the outputs at a defined state before the first command, and the LTC2635 interface keeps wiring simple.

The LTC2635CUD-HMI10 operates from 2.7 V to 5.5 V and draws low quiescent current, suiting compact control and calibration boards. It is specified from 0°C to +70°C, and the 16-Lead QFN outline keeps four channels inside a footprint that would otherwise hold two single converters. Interface timing for the LTC2635 is specified in the manufacturer data sheet.

Every order of the LTC2635CUD-HMI10 ships in 16-Lead QFN packaging with full traceability, RoHS compliant and lead free, and samples plus volume pricing are available on request. The LTC2635CUD-HMI10 is held in stock for quad 10-bit 4.096v precision applications.
