LT LTC1068CN#PBF

50kHz43.14V ~ 11V，±3.14V ~ 5.5V

Overview

The LTC1068CN product family consists of four monolithic clock-tunable filter building blocks. Each product contains four matched, low noise, high accuracy 2nd order switched-capacitor filter sections. An external clock tunes the center frequency of each 2nd order filter section. The LTC1068CN products differ only in their clock-to-center frequency ratio. The clock-to-center frequency ratio is set to 200:1 (LTC1068-200), 100:1 (LTC1068), 50:1 (LTC1068-50) or 25:1 (LTC1068-25). External resistors can modify the clock-to-center frequency ratio. High performance, quad 2nd order, dual 4th order or 8th order filters can be designed with an LTC1068CN family product. Designing filters with an LTC1068CN product is fully supported by FilterCAD™ filter design software for Windows.

The LTC1068CN products are available in a 28-pin SSOP surface mount package. A customized version of an LTC1068CN family product can be obtained in a 16-lead SO package with internal thin-film resistors. Please contact LTC Marketing for details.
