ADI LTC1068-25IG

Универсальный переключаемый конденсатор200 кГц483,14В ~ 11В, ±3,14В ~ 5,5В

Overview

The LTC1068-25IG 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 LTC1068-25IG 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 LTC1068-25IG family product. Designing filters with an LTC1068-25IG product is fully supported by FilterCAD™ filter design software for Windows.

The LTC1068-25IG products are available in a 28-pin SSOP surface mount package. A customized version of an LTC1068-25IG family product can be obtained in a 16-lead SO package with internal thin-film resistors. Please contact LTC Marketing for details.
