Frequently Asked Questions
What is the operating temperature range of the TLE2144AMJB?
The TLE2144AMJB operates over a full military temperature range of -55°C to +125°C, making it suitable for aerospace, defense, and harsh industrial environments. This wide temperature range ensures consistent performance in applications exposed to extreme thermal conditions such as avionics and downhole equipment.
What are the CMRR specifications for the TLE2144AMJB?
The TLE2144AMJB provides a minimum common-mode rejection ratio of 85 dB and a typical CMRR of 108 dB. This high CMRR effectively rejects common-mode noise and interference signals, making it ideal for precision differential signal amplification in noisy industrial and measurement environments.
How many op-amp channels does the TLE2144AMJB contain?
The TLE2144AMJB contains four independent operational amplifier channels in a single 14-pin ceramic DIP package. Each channel features voltage-feedback architecture with internal frequency compensation, providing four precision amplifiers while saving PCB space compared to discrete single op-amp solutions.
What package type is used for the TLE2144AMJB?
The TLE2144AMJB comes in a 14-pin ceramic dual-in-line package (CDIP), which provides hermetic sealing and excellent long-term reliability. The ceramic package is preferred in military and aerospace applications where moisture resistance and mechanical durability are required over extended service life.
What is the typical input bias current for the TLE2144AMJB?
The TLE2144AMJB has a typical bias current of 1.5 µA at 25°C with a maximum of 1.8 µA, and a maximum input offset current of 0.1 µA. These low input current specifications make it suitable for high-impedance sensor interfaces and precision analog circuits where input loading effects must be minimized.
