詳細說明
Utilizing the circuit designs perfected for quad op-amps, this dual op-amp features low power drain, a common mode input voltage range extending to ground/VEE, and single supply or split supply operation. The LM358 series is equivalent to one-half of an LM324. These amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. They can operate at supply voltages as low as 3.0 V or as high as 32 V, with quiescent currents about one-fifth of those associated with the MC1741 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage.
主要特徵
- Wide supply range of 3 V to 36 V (B, BA versions)
- Quiescent current: 300 µA/ch (B, BA versions)
- Unity-gain bandwidth of 1.2 MHz (B, BA versions)
- Common-mode input voltage range includes ground, enabling direct sensing near ground
- 2-mV input offset voltage max. at 25°C (BA version)
- 3-mV input offset voltage max. at 25°C (A, B versions)
- Internal RF and EMI filter (B, BA versions)
- On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. On all other products, production processing does not necessarily include testing of all parameters.
