LH0042CH Description

Short technical summary and product information.

The LH0042CH is a low-cost FET input operational amplifier manufactured by Texas Instruments. It is designed for applications requiring very high input impedance and low input currents without compromising noise, common mode rejection ratio, open loop gain, or slew rate. This internally compensated amplifier is free of latch-up.

 

The device is specified for operation over a temperature range of -25°C to 85°C. Key electrical characteristics include a high open-loop gain of 100 dB typical, a supply voltage range of up to ±22V, and a power dissipation of 500 mW. The input offset voltage is typically 4.0 mV, with an input offset current of 2.0 pA at 25°C.

 

The LH0042CH is pin-compatible with standard IC op amps and comes in a Metal Can package. Its high input impedance and low input bias current make it suitable for applications such as electrometer and photocell amplification, picoammeters, and high input impedance buffers in process control and medical instrumentation systems.
