LTC2654IGN-H12 Quad 12-Bit SPI DAC Quad Industrial 4.096V 16-Lead SSOP Integrated Circuit Chip

The LTC2654IGN-H12 is a quad 12-bit voltage output digital to analog converter from the LTC2654 series, supplied in a 16-Lead SSOP 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 LTC2654IGN-H12 the reference is trimmed to 10 ppm per degree C, and the I grade linearity is specified over the full 12-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 LTC2654.

Data is written through the SPI 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 LTC2654 interface keeps wiring simple.

The LTC2654IGN-H12 operates from 2.7 V to 5.5 V and draws low quiescent current, suiting compact control and calibration boards. It is specified from -40°C to +85°C, and the 16-Lead SSOP outline keeps four channels inside a footprint that would otherwise hold two single converters. Interface timing for the LTC2654 is specified in the manufacturer data sheet.

Every order of the LTC2654IGN-H12 ships in 16-Lead SSOP packaging with full traceability, RoHS compliant and lead free, and samples plus volume pricing are available on request. The LTC2654IGN-H12 is held in stock for quad industrial 4.096v applications.
