The INA103KU is one member of the INA103 family which designed as the low noise, low distortion monolithic instrumentation amplifier.It provides near-theoretical limit noise performance for 200 source impedances and ideal for low-level audio signals such as balanced low-impedance microphones.Its balanced input, low noise and low distortion provide superior performance compared to transformer-coupled microphone amplifiers used in professional audio equipment.
Features of the INA103KU are:(1)low THD+N:0.0009% at 1kHz, G=100;(2)high GBW:100MHz at G=1000;(3)wide supply range:±9V to ±25V;(4)high CMRR:> 100 dB;(5)built-in gain setting resistors:G=1,100;(6)upgrades AD625.And it can be used in high quality microphone preamps(replaces transformers);moving-coil preamplifiers;differential receivers and amplification of signals from strain gages,thermocouples,bright transducers.
The absolute maximum ratings of the INA103KU can be summarized as:(1)power supply voltage:±25V;(2)input voltage range, continuous:±Vs;(3)operating temperature range:-40°C to +85°C;(4)storage temperature range:-40°C to +85°C;(5)junction temperature:+125°C;(6)lead temperature (soldering, 10s):+300°C;(7)output short circuit to common:continuous.If you want to know more information such as the electrical characteristics about the INA103KU, please download the datasheet in www.seekic.com or www.chinaicmart.com.
