Frequently Asked Questions
What supply voltage range and CMRR specification does TLE2142MJGB provide for precision differential amplifier designs?
The TLE2142MJGB operates on supplies up to ±22 V totaling 44 V and delivers 108 dB typical common-mode rejection ratio with a 85 dB minimum, making it suitable for high-voltage differential measurement circuits that must reject large common-mode interference signals.
How does the input bias current specification of TLE2142MJGB affect high-impedance sensor interface designs?
With a maximum input bias current of 1.8 µA and input offset current of only 0.1 µA at 25°C, the TLE2142MJGB introduces minimal voltage error across source impedances up to 1 MΩ, preserving measurement accuracy in thermistor and pH electrode signal conditioning stages.
For which high-reliability environments is the TLE2142MJGB ceramic CDIP package most appropriate?
The ceramic 8-pin CDIP package withstands extended military temperature ranges and harsh vibration environments, making TLE2142MJGB appropriate for aerospace avionics, defense radar signal processors, and satellite analog circuits that require hermetically sealed, radiation-tolerant packaging.
Can TLE2142MJGB replace a standard TL072 in a ±15 V audio console preamp, and what improvement would result?
Yes, TLE2142MJGB operates comfortably at ±15 V and delivers 108 dB CMRR versus TL072's typical 80 dB, providing approximately 28 dB better common-mode noise rejection, which reduces hum pickup in long balanced microphone cable runs by a measurable amount in studio environments.
