The LTC1666/LTC1667/LTC1668 are 12-/14-/16-bit, 50Msps differential current output DACs with high AC and DC performance. They can be configured to provide full-scale output currents up to 10mA and have low power consumption and small package size.
The LTC1666, LTC1667 and LTC1668 are 12‑, 14‑ and 16‑bit differential current output DACs with a 50 Msps update rate. They are built on a high‑performance BiCMOS process and offer high spectral purity (SFDR 87 dB at 1 MHz) and low glitch impulse (5 pV·s). The devices operate from a single +5 V supply and can deliver up to 10 mA full‑scale output current.
The datasheet details electrical characteristics, pin assignments, package dimensions (28‑lead SSOP), and typical application circuits such as arbitrary waveform generation and automated test equipment. It also lists related parts and provides performance graphs for SFDR, THD and other parameters.
