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.

Product Details

This user guide explains the operation of the EVAL-LTC2662-ARDZ for the LTC2662 16-bit, 5-channel, current output DAC, enabling quick prototyping and reduced design time. The device features per-channel SoftSpan™ configuration of 3.125mA to 300mA, a separate supply for each output, and an internal switch to allow any output pin to be connected to V−. The LTC2662 operates on 2.8V to 33V VDD supplies and includes a 1.25V internal low noise reference. Refer to the LTC2662 data sheet, which must be consulted in conjunction with this user guide when using the EVAL-LTC2662-ARDZ.

The evaluation board connects to a PC via SDP-K1 board or directly to microcontrollers via a PMOD connection (requiring SDP-K1 disconnection).
