LND-SENS94
The LND-SENS94
Complete Analog Sensor Polling System
What is the LND-SENS94?
The LND-SENS94 is every analog designers best friend. This IC contains
all of the devices required to poll, filter, amplify and offset AC or DC input
signals. The device has outputs after each stage so that it is possible to
leave out an unneeded stage (like the filter) or to input additional data to
the data stream.
How does it work?
• Connect Vcc and Gnd, connect the clock signal.
• Reset the device by holding M and D low for at least 64 clock cycles.
This will clear all registers.
• Load level shift registers A and B, and set all of the appropriate
level shifts, gains, filter centre frequency, etc.
• Connect input signal to In.
• Uses a simple 8Mhz or oscillator input.
• Device is extremely simple to use and microcontroller friendly.
How Do I get samples?
The LND-SENS94 is available in 84 PGA or 64 pin PLCC packages.
