This application note is a collection of circuits from the first five years of Linear Technology, targeting data conversion, interface and signal processing applications
Application Note 67 (AN67-1) is a circuit collection published by Linear Technology in September 1996. It compiles designs from the company's first five years of operation, specifically targeting data conversion, interface, and signal processing applications.
The document is organized into several categories including Data Conversion, Interface, Filters, Instrumentation, Video/Op Amps, and Miscellaneous Circuits. Key topics include fully differential A/D systems using the LTC1390 and LTC1410, 12-bit DAC applications for system autoranging and current loops, V.35 and RS232 transceivers, various filter designs such as Sallen-Key and ultraselective bandpass filters, and instrumentation amplifier configurations.
The system achieves a throughput rate of up to 625ksps when the selected channel changes with each conversion.
When a new channel pair is selected for every conversion, the sampling rate allows an input signal bandwidth of 39kHz per channel.
Chip Select MUX must be pulled low 700ns before the LTC1410's conversion start input is pulled low.
