Description
General part information
LTC2662 Series
The LTC2662 is a family of five-channel, 16-/12-bit current-source digital-to-analog converters, providing five high-compliance current source outputs with guaranteed 1V dropout at 200mA. The part supports load voltages of up to 32V. There are eight current ranges, programmable per channel, with full-scale outputs of up to 300mA; and the channels can be paralleled to allow for ultrafine adjustments of large currents, or for combined outputs of up to 1.5A.A dedicated supply pin is provided for every output channel. Each can be operated from 2.85V to 33V, and internal switches allow any output to be pulled to the optional negative supply.The LTC2662 includes a precision integrated 1.25V reference (10ppm/°C maximum), with the option to use an external reference.The SPI/Microwire-compatible 3-wire serial interface operates on logic levels as low as 1.71V at clock rates up to 50MHz.ApplicationsTunable LasersSemiconductor Optical AmplifiersResistive HeatersCurrent Mode BiasingProportional Solenoid Drive
