This article introduces a micropower circuit for signal conditioning, which is mainly used in medical, remote data acquisition, power monitoring and other fields. By combining high-performance micropower integrated circuits with appropriate circuit techniques, it is possible to meet the performance requirements of 10 to 12 bits.
The LTC1062 is a versatile, DC accurate, instrumentation lowpass filter with gain and phase that closely approximate a 5th order Butterworth filter. It uses an external (R, C) to isolate the IC from the input signal DC path, thus providing DC accuracy. It also offers lower noise and anti-aliasing advantages.
This document discusses the application considerations and circuits for a new chopper-stabilized op amp. By utilizing chopper-stabilization techniques, this op amp is able to achieve excellent DC performance using relatively primitive components.
This application note presents examples of circuits which offer substantially improved performance over commercially available V→Fs. Various approaches (see Box Section, “V→F Design Techniques”) permit improvements in speed, dy- namic range, stability and linearity.
This application note describes how to achieve complex linear circuit functions, such as data converters and sample-holds, in circuits powered by a single 1.5V cell.
This application note describes the applications of LTC®1043. It is a multi-pole switch that can be used in board-level applications. LTC1043 integrates multiple switches and can achieve multi-channel switching. It controls the switches by a non-overlapping clock.
