The LM2904ST is an integrated circuit (IC) that belongs to the LM2904 series of operational amplifiers. It is a dual operational amplifier, meaning it contains two separate amplifiers within a single package. This IC is widely used in various applications that require amplification, filtering, and mixing of analog signals.
Key Features of LM2904ST:
1. Dual Operational Amplifier: LM2904ST consists of two separate operational amplifiers, allowing it to process two independent signals simultaneously. This feature makes it suitable for applications requiring dual-channel amplification.
2. Low Power Consumption: The IC is designed to operate on low power, making it energy-efficient. This is advantageous for battery-powered devices, as it helps conserve power and prolong battery life.
3. Wide Voltage Range: LM2904ST supports a wide range of power supply voltages, usually ranging from 3V to 32V. This allows for flexibility in different applications, accommodating various power supply configurations.
4. Low Input Bias Current: The IC has a very low input bias current, typically in the nanoampere range. This feature minimizes the impact of the input current on the overall circuit, ensuring accurate signal amplification.
5. High Common-Mode Rejection Ratio (CMRR): LM2904ST offers a high CMRR, typically around 70 dB. CMRR indicates the amplifier's ability to suppress common-mode signals, providing a clean output by rejecting unwanted noise and interference
