描述
The ISL28108, ISL28208 and ISL28408 are single, dual and quad low power precision amplifiers optimized for single supply applications. These devices feature a common mode input voltage range extending to 0. 5V below the V- rail, a rail-to-rail differential input voltage range for use as a comparator, and rail-to-rail output voltage swing, which make them ideal for single supply applications where input operation at ground is important. Added features include low offset voltage, and low temperature drift making them the ideal choice for applications requiring high DC accuracy. The output stage is capable of driving large capacitive loads from rail-to-rail for excellent ADC driving performance. The devices can operate for single or dual supply from 3V (±1. 5V) to 40V (±20V) and are fully characterized at ±5V and ±15V. The combination of precision, low power, and small footprint provide the user with outstanding value and flexibility relative to similar competitive parts. Applications for these amplifiers include precision instrumentation, data acquisition, precision power supply control, and industrial control. The ISL28108 single is offered in 8 Ld TDFN, MSOP and SOIC packages. The ISL28208 dual amplifier is offered in 8 Ld TDFN, MSOP, and SOIC packages. The ISL28408 is offered in 14 Ld SOIC package. All devices are offered in standard pin configurations and operate over the extended temperature range of -40°C to +125°C.

- 应用说明英语PDF 381 KB R13AN0015EU0100 Rev.1.00 2022年5月16日AI 生成的摘要: Low-voltage precision operational amplifiers from Renesas feature ultra-low input offset voltages with on-chip auto-zeroing, ideal for precise sensor signal conditioning in compact applications. Key design considerations include minimizing thermoelectric (Seebeck) voltages caused by PCB junctions and temperature gradients, which can introduce offset errors amplified by high gain. Techniques such as using dummy resistors, maintaining uniform PCB temperature with ground planes, and employing guard rings reduce these errors. The ISL28134 supports precision high-side current sensing with adaptations for high-voltage systems using level shifting via Zener diodes. Output current can be increased by adding an NPN transistor as a current booster, ensuring linear operation within voltage limits. The document provides detailed circuit examples and design guidelines for optimizing performance and minimizing errors in low-voltage op-amp applications.

The VFB amplifier's gain decreases at a dominant pole frequency due to compensation capacitors. Current feedback (CFB) amplifiers include a class AB input amplifier, current mirror, high-impedance stage, and output buffer. CFB amplifiers provide faster switching and higher slew rates by drawing charge/discharge currents directly from supply rails, unlike VFB amplifiers which are limited by biasing current sources.

Signal conditioning includes multiplexing, amplification, filtering, and calibration, ideally performed near the transducer. Transducers convert physical variables to electrical signals, often voltage, with low source resistance preferred.
