Analog Devices Digital to Analog Converters
Analog Devices’ LTC2662 family of five-channel current-source DACs provide high-compliance current source outputs for tunable lasers, optical amplifiers, resistive heaters, current-mode biasing and other applications.
The LTC2662 is available with a per-channel programmable range from 300mA to 3.125mA and with 16-bit or 12-bit resolution. Each output channel operates from a separate supply input ranging from 2.85V to 33V, and internal switches allow any output to be pulled to the optional negative supply.
A 1V guaranteed dropout enables support for loads up to 32V. The LTC2662 integrates an analog mux to monitor voltages and currents as well as a precision 1.25V reference, with the option to use an external reference. Commercial, industrial, and automotive temperature grade parts are available.
- Per-Channel Programmable Output Ranges: 300mA, 200mA, 100mA, 50mA, 25mA, 12.5mA, 6.25mA, 3.125mA
