The LM158J is an operational amplifier (op-amp) integrated circuit (IC) manufactured by Texas Instruments. It is part of the LM158 series, which includes dual general-purpose op-amps designed for a wide range of analog applications.
General Features:
- The LM158J contains two independent op-amps in a single package, making it suitable for applications that require multiple amplifiers.
- It operates with a single or dual power supply voltage, typically ranging from ±2V to ±18V.
- The op-amps have a high input impedance and low input offset voltage, allowing for accurate and precise signal amplification.
- It has a high common-mode rejection ratio (CMRR) and a wide bandwidth, making it suitable for amplifying signals in noisy environments.
Electrical Characteristics:
- The LM158J has a typical input offset voltage of 2 mV, which represents the voltage difference between the inverting and non-inverting inputs that results in zero output voltage.
- The typical input bias current is 30 nA, which is the small current that flows into the input terminals of the op-amp.
- It has a high gain bandwidth product (GBWP) of 1 MHz, indicating the frequency at which the open-loop gain of the op-amp begins to decrease.
Package:
- The LM158J is available in a ceramic DIP (Dual Inline Package) package, which provides robustness and thermal stability.
Applications:
The LM158J op-amp can be used in various analog circuit applications, including but not limited to:
- Signal conditioning and amplification
- Active filters and equalizers
- Voltage and current measurement circuits
- Comparators and oscillators
- Instrumentation and control systems
- Audio amplifiers and mixers
- Voltage regulators and power management circuits
