GXSC OPA GX2350 Compatible OPA2350 for Gas Alarm Detection Signal Amplification

Gas alarms are used to detect combustible or toxic gas leakage and issue alarms, the core device is the sensor for detecting hazardous gases, and its output detection signal is a very weak analog signal, which cannot be directly input into the ADC for processing, and requires an operational amplifier to condition the signal. the OPA GX2350 (compatible with the OPA2350) features a high bandwidth of 38 MHz, low input distortion voltage, and high reliability. It is an excellent choice for analog small signal conditioning in security products such as gas alarms.

Gas alarms to detect toxic gas leakage through the sensor to achieve is, its output detection signal is a weak analog signal, the use of GX2350 (compatible with OPA2350), can provide 38MHz high-bandwidth, rated voltage of 2.7V to 5.5V, to meet the needs of the gas alarm internal sensor output analog small signal amplification.

Gas alarms only require detection of the threshold value of gas leakage and do not require high accuracy. The GX2350‘s input offset voltage of 1mV, input offset voltage temperature drift of 4μV/°C, and low noise of 5nV/√Hz satisfy the gas alarm‘s requirements for the accuracy of the detected signal.

Gas alarms in factories and other harsh environments in the application of the place, need to be in a long-term working condition, so the product reliability requirements are high; GX2350 ESD level of ± 1.5KV, the operating temperature to meet the -45 ~ 125 ℃, can be applied to outdoor application environments.
