The INA333 amplifier module is a precision instrumentation amplifier with low power consumption and excellent accuracy. The gain can be adjusted from 1 to 1000 with a single external resistor. The 3-operation amplifier design, small size and low power consumption make it ideal for a variety of portable applications.
INA333 isdesigned with the industry standard gain equation: G = 1 + (100k Ω/RG) - details can be found in the INA333 datasheet.
The integrated 3.3 V low dropout LDO regulator chip supplies the INA333 amplifier directly with power. The amplifier uses a single-ended power supply mode, V- is connected to GND and V+ is connected to the 3.3 V LDO output.
Field of application
Bridge amplifiers, electrocardiogram amplifiers, pressure sensors, medical instruments, portable instruments, thermocouple amplifiers, sensor amplifiers for resistive temperature detectors (RTD), data acquisition, etc.
