Key Features
- 2.3 MHz continuous-time lowpass filter cutoff requiring no external resistors or capacitors
- Low noise design suitable for precision signal conditioning and anti-aliasing before ADC inputs
- Operates from dual ±5 V or single 5 V supply for flexible power architecture compatibility
- 8-pin SO-8 package enabling compact PCB integration alongside signal chain components
Applications
LTC1566-1CS8 is used as an anti-aliasing filter ahead of high-speed ADCs in data acquisition systems, communications receivers, and medical imaging equipment. Its continuous-time topology eliminates clock-related noise and sampling artifacts that affect switched-capacitor filters. The single 5 V supply option makes it easy to integrate into modern low-voltage signal processing boards without a negative supply rail.

Frequently Asked Questions
What is the cutoff frequency of LTC1566-1CS8 and what filter order does it implement?
LTC1566-1CS8 implements an 8th-order continuous-time lowpass filter with a cutoff frequency of 2.3 MHz. The 8th-order rolloff provides approximately 160 dB per decade of attenuation beyond the cutoff, making it highly effective at suppressing aliasing artifacts in front of ADCs sampling above 4 MHz.
Can LTC1566-1CS8 operate from a single-supply system, and what voltage is required?
Yes, LTC1566-1CS8 can operate from a single 5 V supply in addition to its nominal dual ±5 V supply configuration. This single-supply flexibility allows designers to use it in battery-powered or USB-powered signal conditioning circuits without generating a negative rail, simplifying power supply design and reducing BOM cost.
How does using LTC1566-1CS8 reduce BOM complexity compared to a discrete active filter implementation?
LTC1566-1CS8 integrates an 8th-order 2.3 MHz lowpass filter into a single SO-8 chip with no external timing resistors or capacitors needed, replacing 8 or more op-amps and 16 or more passive components required for an equivalent discrete design. This reduction to 8 pins cuts PCB area by several square centimeters and eliminates component tolerance matching concerns.
