AMEYA360:Dioo independently developed DIA2641 through vehicle regulation certification

　　Recently, Jiangsu Diao Microelectronics Co., LTD. (hereinafter referred to as Diao Micro) independent research and development operational amplifier series products DIA2641 passed AEC-Q100 vehicle gauge reliability certification.　　In recent years, the automobile industry presents the development trend of electrification, intelligence and sharing. The rapid upgrading of the industry has put forward higher requirements for chip performance, reliability, adaptability and security.　　The DIA2641 is a high-bandwidth, high-voltage swing rate, high-voltage op-amp product designed to provide optimal performance in high-voltage systems, providing rail-to-rail output even under heavy load conditions with fast output conversion rates (150 V/? s) Ensure rapid response ability of signal from input to output.　　DIA2641 complies with AEC-Q100 Grade 1 high reliability certification standards and PPAP procedures, and is widely used in motor control, body control, virtual instrument, intelligent cockpit and other automotive electronic markets. It is now in mass production and delivery stage.　　DIA2641 Main parameters:　　· Support AEC-Q100 Grade 1 temperature rating requirements (TA = -40℃ to +125℃);　　· Operating voltage range: 2.7V to 13.2V;　　· High gain bandwidth product: 90MHz (Vs=5V);　　· Ultra-high voltage swing rate: 150V/μs;　　· Input offset voltage: 11mV (maximum);　　· Open-loop voltage gain: 101dB;　　· PSRR: 85dB (Vs=5V);　　· Common-mode rejection ratio: 90dB;　　· Support rail to rail input and output;　　· Establishment time: 100ns (VOUT = 2Vpp, accuracy ±1%, CL=8pF, Vs=5V);　　· SOT23-5 green package in line with environmental protection concept.　　High bandwidth gain product (GBW)　　The gain-bandwidth product is an important parameter used to measure the performance of an operational amplifier. This parameter represents the product of gain and bandwidth. The unit gain bandwidth of the operational amplifier, which refers to the -3dB bandwidth when the operational amplifier gain is 1, is numerically equivalent to the gain bandwidth product of the operational amplifier.　　High voltage swing rate (SR)　　Voltage swing rate is the conversion rate of the output voltage of an operational amplifier. Is an indicator of the speed of the operational amplifier, indicating the response ability of the operational amplifier to the speed of signal change, is a parameter to measure the operating speed of the operational amplifier when the large signal action.　　Power supply rejection ratio (PSRR)　　PSRR of operational amplifier refers to the change of input offset voltage caused by the change of supply voltage. Therefore, PSRR can be measured by referring to the method of measuring the offset voltage. From the change of the power supply voltage, △ Vcc and then from the measurement, you can calculate the PSRR.
