![]() ![]() How to lay out a PCB for high-performance, low-side current-sensing designs AA)ĭesign Guidelines for Devices with LM324/LM358 Cores (Rev. ![]() Industry-Standard Dual Operational Amplifiers datasheet (Rev. The LM358B and LM2904B amplifiers are available in micro-sized packaging, such as the SOT23-8, as well as industry standard packages including SOIC, TSSOP, and VSSOP. High ESD (2 kV, HBM) and integrated EMI and RF filters enable the LM358B and LM2904B devices to be used in the most rugged, environmentally challenging applications. The LM358B and LM2904B op amps simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage maximum of 3 mV (2 mV maximum for LM358BA and LM2904BA), and lower quiescent current of 300 ♚ per amplifier (typical). These devices provide outstanding value for cost-sensitive applications, with features including low offset (300 µV, typical), common-mode input range to ground, and high differential input voltage capability. The LM358B and LM2904B devices are the next-generation versions of the industry-standard operational amplifiers (op amps) LM358 and LM2904, which include two high-voltage (36 V) op amps. On all other products, production processing does not necessarily include testing of all parameters. On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted.Internal RF and EMI filter (B, BA versions).Common-mode input voltage range includes ground, enabling direct sensing near ground.Unity-gain bandwidth of 1.2 MHz (B, BA versions).Quiescent current: 300 ♚/ch (B, BA versions).Wide supply range of 3 V to 36 V (B, BA versions).parametric-filter Precision op amps (Vosparametric-filter High-speed op amps (GBW ≥ 50 MHz).parametric-filter General-purpose op amps.parametric-filter Special function amplifiers.parametric-filter Programmable & variable gain amplifiers (PGAs & VGAs).parametric-filter Operational amplifiers (op amps).parametric-filter Instrumentation amplifiers.parametric-filter Fully differential amplifiers.parametric-filter Difference amplifiers. ![]()
