Description
DC Signal Amplification Weak Signal Acquisition ICL7650 Single Supply Op Amp Chopper Op Amp Operational Amplifier
Name
ICL7650 Chopper amplifier
Size
50mm X50mm
Supply voltage range
±5V
Decription
This module is used to do weak signal acquisition front-end to amplify the DC signal. The main difference between the usual AC amplifiers is that they can chopper-amplify DC signals at a certain frequency. And the maximum output offset voltage and bias current is very small, very practical and weak signal acquisition. This module is compatible with TI's TCL2652 chopper amplification chip.
The main features Guaranteed maximum input offset voltage for full temperature range Input offset voltage low long-term temperature drift Guaranteed Maximum Input Bias Current -10pA Very Wide Common Mode Voltage Range - +3.5V to -5V Reduced supply current - 2 mA Guaranteed minimum output source/sink current Very high gain - 150db High-pressure slew rate -2.5V/μs Wideband - 2MHz Unit gain compensation Clamp the circuit to avoid overload recovery problems and allow the use of comparison Very low chopping peak input and output Improved, direct replacement of industry-standard ICL7650 and other two-source components Effective lead-free plus annealing (RoHS)
Absolute maximum rating Power supply voltage (V+-V-)-18V Input voltage - (V + +0.3) to (V--0.3) Upper oscillator control pin voltage -V+ to V- Output short circuit duration - indefinite Current to any pin -10mA Working conditions Temperature range ICL7650SC -0° C to +70° C Maximum junction temperature (plastic package) - +150 °c Maximum storage temperature range - 55" C to +150"C Lead-free PDIPs can be used for through-hole wave soldering. They are not intended for reflow soldering applications.
