LTC2662HUH-16#PBF

LTC2662HUH-16#PBF is a five-channel, 300mA current-source output 16bit SoftSpan DAC. It provides 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 SPI/Microwire-compatible 3-wire serial interface operates on logic levels as low as 1.71V at clock rates up to 50MHz. Application includes tunable lasers, semiconductor optical amplifiers, resistive heaters, current mode biasing, proportional solenoid drive.

• Per-channel programmable output ranges: 300mA, 200mA, 100mA, 50mA, 25mA, 12.5mA, 6.25mA and 3.125mA
