LTC2602

The LTC2602, LTC2612, and LTC2622 are a series of dual, rail-to-rail voltage-output Digital-to-Analog Converters (DACs) from Linear Technology (LT). These devices are available in 16-bit (LTC2602), 14-bit (LTC2612), and 12-bit (LTC2622) resolutions, offering flexibility for various precision requirements.

Designed for single-supply operation, they feature a wide supply voltage range of 2.5V to 5.5V. The DACs utilize a simple SPI/MICROWIRE compatible 3-wire serial interface, capable of operating at clock rates up to 50MHz. They incorporate built-in high-performance output buffers and are guaranteed monotonic.

Key features include low power consumption, individual channel power-down capabilities, ultralow crosstalk between DAC channels, and high rail-to-rail output drive. The series also includes a power-on reset circuit that ensures outputs rise less than 10mV above zero scale during power-up and remain at zero scale until a valid write and update occur.

These DACs are housed in a tiny 8-lead MSOP package, making them suitable for space-constrained applications. They are well-suited for applications such as mobile communications, process control, industrial automation, instrumentation, and automatic test equipment.
