aMG SQLite Database Server Datasheet

aMG SIGCON-A is a simple general purpose op-amp breakout board. It has been designed to be highly flexible. You can create any op-amp application circuits such as inverting, non-inverting amplifier, voltage follower, LP filter, etc., by soldering some R, C or wire jumper at the specific positions using reference circuit diagrams. 

Features 
• Based on LM7321, single rail-to-rail input and output amplifiers.
• Wide operating voltage ranges 2.5V to 32V. 
• Hi output current +65 mA / –100 mA.
• Gain bandwidth product 20 MHz.
• Capacitive load tolerance unlimited.
• Input common mode voltage 0.3V beyond rails.
• Temperature range –40°C to 125°C.

Signal Conditioning Design Guideline

• Come with MAX31855KASA+ Cold-Junction Compensated Thermocouple-to-Digital Converter.
