The EL2126CS-T13 is a high-speed single-channel operational amplifier integrated circuit (opamp) manufactured by Elantec Semiconductor. It is suitable for applications where high-speed performance, stability and low-offset voltage are required. This opamp is used in a variety of instrumentation, linear amplifier and buffer amplifier circuits.The EL2126CS-T13 is designed as a rail-to-rail single-channel opamp, meaning that it is capable of outputting signal swings all the way from the supply potential at the negative rail to the supply potential at the positive rail. This makes it a good choice for instrumentation circuits which require high-speed performance, wide dynamic range, and low offset voltage. The EL2126CS-T13 has a differential input voltage range of ±8V and an output voltage range of 0V to +13V. It features a slew rate of 5V/μs, a low input bias current of 1.5pA and a guaranteed maximum offset voltage of +/-5mV.The EL2126CS-T13 is typically used in instrumentation, linear amplifier and buffer amplifier circuits. In instrumentation, the EL2126CS-T13 is a good choice for transducer and sensor signal amplifications due to its high-speed performance and wide dynamic range. In linear amplifiers, it can be used to amplify low-level signals with low noise, distortion and increased stability. In buffer amplifiers, it can be used to isolate signals from loading effects and provide impedance and voltage gain. The working principle of the EL2126CS-T13 is based on the voltage-follower source-follower (VFSF) topology. It employs a differential input stage followed by a source-follower output stage, which together provide high gain and low output impedance. This opamp comprises three transistors for the input, one for the output, and two for the bias current circuit. The input differential pair consists of p-channel and n-channel MOSFETs with gate, source and drain connections. This enables the opamp to provide high performance due to its low input bias current and low offset voltage. The output stage is composed of an n-channel MOSFET with gate, source and drain connections, and a 2nd-stage voltage buffer to the opamp output. This provides the EL2126CS-T13 with excellent performance characteristics such as low output impedance, high speed, low harmonic distortion and excellent linearity. The EL2126CS-T13 is a high-performance integrated circuit designed to meet the needs of instrumentation, linear amplifier and buffer amplifier circuits. Its high-speed performance, low offset voltage and wide dynamic range make it an ideal choice for these applications. It works on the basis of the voltage-follower source-follower topology, which features low bias current, low output impedance and excellent linearity. The combination of these features provides the EL2126CS-T13 with superior performance making it well-suited for use in demanding applications.
