This screening circuit board can be widely used in single-operational amplifier and dual-operational amplifier performance evaluation. By accessing different types of operational amplifiers, it can effectively determine whether IC can be amplified, greatly improving efficiency of integrated circuit screening and testing. With ability to roughly judge conversion rate of operational amplifiers, it can help users to identify counterfeit high-speed chips in market, and effectively avoids system performance degradation caused by use of low-speed chips, which is highly practical, and greatly expands its application scope in various circuit designs and projects. Features: Premium Material: It adopts premium quality printed circuit board materials, it is designed with high reliability and stable maintenance performance, and nice interchangeability, to ensure stable operation and long durability of printed circuit board. IC Amplification Judgement: This screening circuit board can be widely used in single operational amplifier and dual operational amplifier performance evaluation. By accessing different types of operational amplifiers, it can effectively determine whether IC can be amplified, greatly improving efficiency of screening and testing integrated circuits. Conversion Rate Judgement: With ability to roughly judge conversion rate of operational amplifiers, it can help users identify counterfeit high-speed chips on market, and effectively avoids system performance degradation caused by use of low-speed chips, which is highly practical. Single Operational-AMP Models: Supports single operational-amp and dual operational-amp test, supports LM741, LF356, NE5534, TL071, TL081, OP07, and other standard package single operational-amp, ensuring flexible use in various application scenarios. Dual Operational-AMP Models: Supports LM358, NE5532, TL072, TL082, MC1458, RC4558, OP275, AD827, and other standard package dual operational-amps, which greatly broadens scope of its application in different circuit designs and projects. Specifications: Name: Operational Amplifier Material: printed circuit board Working voltage: 12VDC&nbsp; Working current: More than 100mA Item size: 92 * 57 * 17mm / 3.62 * 2.24 * 0.67in Package size: 93 * 58 * 20mm / 3.66 * 2.28 * 0.79in Package weight: 35g / 1.23ounce Packing List: 1 * Operational Amplifier
