The LTC1066-1 from Linear Technology is a clock‑tunable, DC‑accurate low‑pass filter available in an 18‑lead SO‑wide package. It provides 14‑bit DC gain linearity, a maximum DC offset of 1.5 mV, and can be configured for elliptic or linear‑phase response via pin 8.
The device operates from a single 5 V supply up to +8 V, drives 1 kΩ loads with 0.02 % THD, and offers an input impedance of 500 MΩ. Detailed electrical characteristics, pin functions, and typical performance graphs are included for design integration.
